IMDSP Electronic Newsletter Vol. 1, No. 3 Editor: Joel Trussell, (hjt@ecehjt.ncsu.edu) ********************************************************************** Contents: Policy and Purpose Mailing List People: Transitions Journal Tables of Contents Dissertation Abstract Conferences and Workshops ********************************************************************** Policy and Purpose The purpose of this newsletter is to keep the multidimensional signal processing and image processing community informed of current events and publications in the areas. One of the major tasks of this newsletter is to list the Tables of Contents of the most important journals in our area. This will be of great benefit to those of us who don't subscribe to a long list of journals and don't go to the library as often as we should to look through the current issues of non-IEEE journals. Lists of titles and authors from sessions at conferences are also appropriate in this regard. A second function is timely communication of news events, news of new hardware or software, notes of popular magazine or newspaper articles of interest, News of people in the MDSP area (awards, moves), etc. Since the newsletter is composed almost totally of contributed items, it is up to the readership to provide desired information to the editor. The editor will use his judgement as to the proper length and appropriateness of contibutions. The ToCs in this newsletter include: IEEE Transactions on Image Processing IEEE Transactions on Signal Processing IEEE Transactions on Circuits and Systems II: IEEE Transactions on Pattern Analysis and Machine Intelligence Journal of Electronic Imaging CVGIP SMPTE Journal Signal Processing Missing from this list is: IEEE Trans on Video Technology IEEE Trans on Medical Imaging Optical Engineering Journal of the Optical Society Multidimensional Systems and Signal Processing Can we get volunteers for these? ******************************************************************** In the next newsletter I will publish the mailing list for this newsletter. After long discussions, virtually everyone I talked with agreed that the advantages of this outweighed the disadvantages. Other newsletters publish their subscription lists in order to facilitate communication in the technical community. If you do not wish to have your name and email address published, please let me know. ******************************************************************** Finally a personal information item: A. Murat Tekalp will be on sabbatical leave from the University of Rochester next academic year, between Sept. 1st 1992 to June 1st 1993 in Bilkent University, Ankara, Turkey.

[This paper describes an inter-/intra-frame vector quantization (VQ) coding system, which can achieve adequate performance for video conferencing or videophone with a simple decoding technique (table lookup), and can provide a robust universal codebook for most real world images. The proposed system is constructed by several methods which are motion compensated prediction with conditional pixel replenishment, interframe-VQ coding, intraframe-VQ coding, mean-cut algorithm, and k-d tree structure. Experimental results show that the performance of this system is adequate in spite of the simplicity of the decoder. The test pictures used in this study are captured directly from broadcast video in color with size 144 x 176 pixels.] [abs] Texture Segmentation Based on a Hierarchical Markov Random Field Model, Hu RM & Fahmy MM, p285-305. [This paper presents a new texture segmentation technique for both supervised and unsupervised segmentation. The textured images under study are modeled by a proposed hierarchical Markov random field (MRF) model. This model is formed by combining the binomial model for textures and the multi-level logistic model for region distributions. The supervised segmentation is achieved by a new algorithm which can reach the global maxima of the posteriori distribution even if the textures are modeled by an MRF model. For unsupervised segmentation, a new parameter estimation scheme is proposed to estimate the model parameters directly from a given image. The new technique is verified by a variety of textured images, such as synthesized textures, natural textures and aerial images, in both supervised an ****************************************************************** TOC FOR Signal Processing, V27 N1, APR 92 [abs] Adaptive Rank Order Based Filters, Salembier P, p1-25. [This paper is devoted to the adaptive optimization of a class of nonlinear filters referred to as rank order based filter. This class includes, as special cases, classical rank order filters and morphological filters with flat structuring element. The definition highlights their common origin based on sorting operations. It is shown how to adapt the filter mask and/or the rank parameter in order to minimize a criterion such as the mean square error (MSE) or the mean absolute error (MAE). The proposed algorithms are similar to the LMS algorithm and one of their major advantages is their simplicity. The algorithms derivation is achieved by replacing the input/output relation of the filter involving sorting operations, by an implicit formulation using only sign functions. Several practical examples for one-dimensional signals are described illustrating the convergence properties and the difference between MAE and MSE optimization. Finally, the algorithms are applied to various real images, illustrating the ability of adaptive nonlinear filtering in coping with textures, in removing different types of noise and in dealing with non-stationary signals.] [abs] Volumetric Reconstruction from Object Silhouettes: A Regularization Procedure, Grattarola AA, p27-35. [A regularization procedure for the volumetric reconstruction of objects from occluding contours is presented. It exploits a simple geometrical constraint on the intersection of the volumes generated by backprojecting the object silhouettes and minimizes the volume reconstruction error with respect to the extrinsic parameters, i.e. position and orientation, of each view. The results of simulation tests are described, showing very good improvements in the reconstruction quality.] [abs] Behavioral Object Recognition from Multiple Image Frames, Delbimbo A & Nesi P, p37-49. [Analysis of image sequences is a well-established research subject in computer vision. Main goals are to derive the 3D shape of moving objects, as well as to detect object motion law for prediction and tracking. Nevertheless, the object behavior in the frame sequence can also be directly used for object recognition and motion classification. This implies regarding motion as a property of the object and is particularly useful when the object form provides little or no discrimination power. In this case. the behavior can give crucial hints for classification. In this paper, two different motion models are defined for moving objects which are regarded as a single whole and for composite objects with coordinated moving subparts, respectively. A reduced set of parameters is adopted as descriptors of the actual object motion and used for behavior-based object recognition and classification.] [abs] Image Reconstruction on Hypercube Computers: Application to Electron Microscopy, Zapata EL & Benavides I & Rivera FF & Bruguera JD, p51-64. [Filtered backprojection is a popular algorithm for the reconstruction of n-dimensional signals from their (n - 1)-dimensional projections (in the sense of line integrals). Here we specifically treat the problem of the 3-dimensional (3D) reconstruction of an object from its 2-dimensional (2D) projection images. In this work we perform the implementation of the filtered backprojection method in hypercube computers. The parallel algorithm is general in the sense that it does not impose any restriction in the problem space dimensions and is adaptable to any hypercube dimension. The flexibility of the algorithm is rooted in the methodology developed for embedding algorithms into hypercubes. Finally, we analyze the complexity of the parallel algorithm and apply the parallel algorithm to the 3-dimensional reconstruction of the oligomer formed by the chaperonin GroEL from E. coli.] [abs] A Generalized Hidden Markov Model with State Conditioned Trend Functions of Time for the Speech Signal, Deng L, p65-78. [The standard hidden Markov model (HMM) and the hidden filter model assume local or state-conditioned stationarity for the modeled signal. In this work we generalize these models and develop the 'trended HMM' to allow the local, as well as the global (via a Markov chain), non-stationarity to be represented in the model. The mathematical structure of the trended HMM can be described by a discrete-time Markov process with its states associated with distinct regression functions on time, or alternatively by a 'deterministic trend plus stationary residual' time series with its parameters governed by the evolution of a Markov chain. The EM algorithm is applied to obtain closed-form re-estimation formulas for the model parameters. Compared with the types of HMMs developed in the past, the trended HMM is a more faithful and more structured representation of many classes of speech sounds whose production involves strong articulatory dynamics. As such, it is expected to be a more suitable model for use in speech processing applications.] [abs] Phase Estimation by Bispectrum: A Group Delay Approach, Narasimhan SV & Reddy GR & Plotkin EI & Swamy MNS, p79-86. [In this paper, a new method of extracting the system phase from that of the bispectrum, based on a group delay approach has been proposed. The phase estimation is achieved by relating the bispectral phase to the system group delay function. The proposed method does not make any assumptions regarding the phase values at any of the frequencies, uses all the bispectral phase data, does not involve any solution of a system of equations and does not require any phase unwarping, It is applicable to moving average (MA), autoregressive (AR) and autoregressive moving average (ARMA) systems and not just limited to MA systems. Even with fewer triple correlation lags. its performance is either superior to or at par with those of Lii and Rosenblatt's method or Brillinger's method. The proposed method has been evaluated for ARMA systems.] [abs] Optimal Weighted Phase Equalization According to the L Infinity Norm, Lang M, p87-98. [In this paper optimal phase equalization with all-pass filters using the Chebyshev error criterion is considered. The most important results of non-linear approximation theory as well as a Remez-type algorithm for the construction of the best solution are presented. Some examples illustrate the efficiency of the new method. Linear and quadratic phase functions can be approximated, too.] [abs] Parameter Estimation of Decaying Exponentials by Projection on the Parameter Space, Karrakchou M & Vidal J & Vesin JM & Feihl F, p99-107. [We propose in this paper a new estimation method for the parameters of a linear combination of exponentials corrupted by some noise. It is shown that this method does not require any a priori information about the nature of the noise probability density. The algorithm is used to estimate parameters of synthetic signals and to estimate effective pulmonary capillary pressure. This algorithm is compared to the method of Kumaresan and Tufts which is based on linear prediction and singular value decomposition. Our experiments demonstrate increased accuracy over the method of Kumaresan and Tufts.] ************************************************************************** Contributed by Gordana Pavlovic.

[NHK has developed a new high-performance camera tube for producing superior pictures, with a sensitivity 100 times that of conventional camera tubes or charge-coupled devices (CCDs). The new tube, called the Super-HARP, uses the phenomenon of avalanche multiplication in a thin target layer and is capable of producing high picture quality in a wide range of conditions, from daylight to moonlight. Its sensitivity has made it possible to develop many new kinds of programs, and it will certainly bring about changes in the basic techniques of TV program production and studio lighting.] [abs] Measurement and Testing of CCD Sensors and Cameras, Kutzner J & Hightower L & Pruitt C, p325-328. [As more and more broadcast and production facilities face replacing tube cameras in field and studio applications, it is critical that the decisions be based on test results that accurately measure the problems as well as the benefits of using CCD sensors. What was learned at PBS through its recent experiences in camera evaluation may shed some light for others.] [abs] Logarithmic A/D Converters Used in Video Signal Processing Systems, Glenn WE & Glenn K & Glatt TL, p329-333. [Analog-to-digital (AID) converters that can be clocked at video rates and that have a logarithmic transfer characteristic between the input and output are now available. Video signal processing using this transfer curve can more closely match the performance of the visual system than normal signal processing. This reduces the visibility of contouring when signals are digitized. It also facilitates the production of color signals that are independent of luminance, thus reducing many of the artifacts in saturated colors. Comparisons are shown on real images between standard processing and improvements that can be achieved by using digital processing logarithmic signals.] [abs] The Opportunities of Signal Monitoring in a Large Serial Digital Plant, Wilson R, p334-335. [When faced with the technical planning of a digital television facility, signal monitoring is a topic that appears at first to be of low priority. This was the case at NBC while structuring the initial plans of operation in a digital plant. First assumptions were to use waveform, vector, and picture monitors similar to those used today. Perhaps a minor modification would be required to convert the serial digital data stream to an analog waveform. The analog waveform can then be displayed on the same types of cathode ray, tubes (CRTs) that are presently used. After further research it was discovered that additional circuitry would incur an alarming amount of extra costs. Further analysis cast more doubts when the monitoring philosophy was considered. What is the point of monitoring analog wave forms that had previously been digitized? ln summary, we had a scenario where the analog test signal had little or no value in the digital domain and could give misleading results if interpreted in the analog domain.] [abs] Stability of Cellulose Ester Base Photographic Film I Laboratory Testing Procedures, Adelstein PZ & Reilly JM & Nishimura DW & Erbland CJ, p336-346. [This article describes the studies done on the chemical stability of photographic film by incubation of a dozen different materials at five temperatures and four relative humidities (RH). Property changes were followed using Arrhenius plots. Predictions of useful life at room temperature storage were very dependent upon the property measured with base acidity being the most sensitive indicator At 50% RH, the gelatin layer had greater stability than that of the base. There was no consistent difference between the stability of the uncoated base and emulsion-coated base.] [abs] Stability of Cellulose Ester Base Photographic Film II Practical Storage Considerations, Adelstein PZ & Reilly JM & Nishimura DW & Erbland CJ, p347-353. [An analysis is given of the incubation studies described in the preceding paper (Part I), which featured over 15,000 measurements. The projected life expectancy at room temperature of different safety cellulose ester base films was quite similar A nitrate base film also had a projected life similar to that of several cellulose triacetate base films. Film life was dramatically increased when the relative humidity (RH) was lowered below 50%, The improvement in stability offered by lower storage temperature was similar for different materials.

While these debates take place, NTSC production will continue. NTSC studios will be built, and it can be predicted with a high degree of confidence that the major part of future production facilities will be digital. In fact digital studios are being constructed now; their proliferation is limited mainly by the lack of standardization and systems hardware.] [abs] An Advanced High Resolution, High Brightness Lcd Color Video Projector, Tsuruta M & Neubert N, p399-403. [A liquid crystal device (LCD) projector has been developed that yields bright, high-resolution color television pictures on screens as large as 120 in., diagonally measured. It possesses a compact, single-lens optical system in which color registration, or convergence, is permanently established and set during manufacturing. The user may therefore relocate the projector and change the projected image size at will, and without the necessity to perform color convergence adjustments afterward. Anamorphic lenses have been developed that permit this to project "wide-screen" pictures with an aspect ratio of 16:9, in addition to normal lenses that yield a standard television picture of 4:3 aspect ratio. Anamorphic lenses have been developed as well for television cameras so that the widescreen pictures can be acquired by conventional NTSC color cameras and recorded with standard NTSC-format videocassette recorders.] [abs] Video Compression and Noise Reduction Using Transform Subband Coding and Adaptive Amplitude Modulation, Baylon DM & Lim JS, p404-406. [This article presents the basic ideas behind transform and subband representations of a signal. Although transform and subband representations appear to be different, in fact, they are equivalent. This theoretical relationship gives useful insights into the design of video processing and compression systems. An application of this result to the design of an adaptive amplitude modulation/demodulation (AM/DM) system for noise reduction of images is described. Also discussed is the AM noise-reduction technique for additive noise, and a method is presented to reduce the AM side information by exploiting the transform representation of an image.] [abs] Digital Real Time Editing for Audio Mastering: The Dream(TM) System, Feldman NB, p407-410.

The digital hierarchy concept is a novel approach to transcoding digital video among several data rates. Also described are some of the industry requirements that the authors believe will be important in the era of HDTV, and the ability of a digital hierarchy to satisfy them is evaluated.] [abs] New Registration Error Detecting System for 3-Tube Hdtv Cameras, Mimura I & Tomura N & Murata N, p471-474. [A registration error detection system applicable to a real-time registration correction system is proposedregistration errors by using live pictures. Conventional block-by-block pattern matching and a new technique that finds and rejects false detection errors are used. False errors are completely rejected based on picture characteristics, including the spatial-frequency component, chrominance component, pattern-matching value, and detecting-error value difference among blocks. The proposed system is examined with a computer-picture simulation system. It is confirmed that the system detects accurate (less equal 1 pixel/line) registration errors and rejects false detection errors completely. When the system is implemented into a digital large-scale integrated circuit (LSI), estimated detection time is about 200 msec. The system enables a real-time, fully automatic registration correction system.] [abs] Experimental Digital Vcr with New Dct Based Bit Rate Reduction and Channel Coding, Endoh N & Kizu S & Odaka T & Ogi K, p475-480. [To achieve a more compact and longer-playing videocassette recorder (VCR), the number and the size of its recording bits must become smaller. The authors have achieved a data rate of 28 Mbits/sec for a component-coded video that normally requires approximately 200 Mbits/sec, maintaining high picture quality with less noticeable degradation by using a new discrete cosine transform (DCT)-based bit-rate reduction method. The authors have developed a data format based on the triple Reed-Solomon product code and a new 8/14 modulation scheme to make the recording density higher. An experiment showing the feasibility of the authors' new system concept is discussed in this article.] [abs] Continuously Variable, Remote Color Temperature Adjustments for Metal Halide Lamps in Cinematographic Applications, Ketsdever A & Omens W & Muntz EP, p481-487. [One approach to achieving ratemperature has been investigated, the Liquid Dynamic Color Filter (LDCF). A thin layer of liquid - a pure iodine and ethyl alcohol solution - is continuously circulated, allowing the concentration of the solution to be changed and introduced to the filter layer. A spectrometer and color temperature meter are used to investigate the effect of the solution's concentration on a typical HMI lamp's color temperature. It was found that the color temperature of the filtered HMI lamp was a well-behaved, smooth function of the concentration. Color temperatures in the 5600-degrees K to 3000-degrees K range have been obtained. Spectrometer tests show that the iodine and ethyl alcohol solution does not introduce spectral discontinuities. However, the solution has shortcomings as an LDCF filtering solution. This is evident when the color correction and light balance ratios are investigated. Future work on improvements to the filter solution is planned.] [abs] Communication Networks for the Remote Control of Television Equipment: Interim Report from the Smpte Ad Hoc Group On Esnet, Walker MS, p488-494. [For over 12 years, SMPTE and EBU committees have been working in cooperation on machine-control standards for television equipment. This work has resulted in the highly successful ESbus hardware specification, ANSI/SMPTE 207M, which has been accepted worldwide, resulting in a number of devices with 9-pin connectors and RS-422 control. The time has come for a higher performance level in a hierarchy of control systems. The Ad Hoc Group on ESnet has been looking at various candidate networks, and has made recommendations for a communications network and control protocol to its parent committee. The issues involved in selecting a network are discussed in this article.] [abs] How Closed CaAdvanced Television Captioning System of Tomorrow, Armon C & Glisson D & Goldberg L, p495-498. [The North American closed-captioning system has opened the world of television to millions of deaf and hard-of-hearing viewers. Soon, with the implementation of the Television Decoder Circuitry Act, closed captions will become commonplace in U.S. homes. The current system for delivering NTSC closed captions is economical and reliable, but many improvements are needed. The next standard for program-related data should be an open, flexible, and international architecture for the enrichment of video programming through captioning, subtitling, and other services, with character sets to accommodate as many alphabets and languages as possible and enough bandwidth to serve multiple needs simultaneously.] The Post Experience: March 27-28, 1992, Toronto, Ontario, Canada, [editorial], Bishop B, p498-500.

Ozkan Advisor: A. M. Tekalp Granting Institution: University of Rochester Date of Acceptance: June 19, 1992 Further Information: Contact Mehmet K. Ozkan Thomson Consumer Electronics, Research and Development Labs 600 N. Sherman Drive, MS. 1-399 Indianapolis, IN 46201-2598 e-mail: tcemail!pc!Mehmet_Ozkan@uunet.UU.NET We propose novel methods for multiframe filtering of image sequences for spatiotemporal noise reduction, image deblurring and high-resolution image reconstruction. The restoration of space-varying blurred single frame images is also addressed as a special case. For space-varying blur identification, we employ a Local Fourier Transform analysis. We extend the projections onto convex sets (POCS) method for space-varying image restoration. This space-varying POCS method is compared with the 2-D Kalman filtering approach. For spatiotemporal noise filtering, we propose two novel adaptive motion-compensated filters, the spatiotemporal linear minimum mean square error (LMMSE) filter and the adaptive weighted averaging (AWA) filter. The AWA filter is well suited for sequences with abruptly changing scene content. We also develop novel approaches for multiframe Wiener filtering for the restoration of noisy and blurred image sequences. The temporal correlation between the frames are incorporated into the proposed multiframe Wiener filtering algorithms either through explicit use of cross-correlation matrices, the cross-correlated multi-frame (CCMF) filter, or indirectly through the use of inter-frame motion estimates, the motion-compensated multi-frame (MCMF) filter. Another contribution of this thesis is in the area of reconstruction of high-resolution still frames from low-resolution image sequences. We propose a two-step interpolation-restoration method and an improved POCS method to obtain higher-resolution images. All proposed methods are demonstrated on simulated images as well as on a real video sequence and photographically blurred image. ************************************************************************** IMAGE PROCESSING: THEORY AND APPLICATIONS June 14-16, 1993 Villa Nobel, San Remo, ITALY An International Conference sponsored by IEEE North Italy Chapter IAPR Italy Chapter EURASIP All aspects of image processing including but not limited to: Picture and Video Coding Filtering, Color and Texture Segmentation, Feature Extraction and Motion Analysis Classification and Understanding Applications Submit five (5) copies of an extended summary (4 pages) to the Conference Secretariat for review by October 10, 1992 Notification of Acceptance: December 10, 1992 Camera Ready Copy: February 6, 1993 Conference Secretariat E.
