conference on algorithms for Synthetic Aperture Radar Imagery

作者： WINTER, EM SCHLANGEN, MJ HENDRICKSON, CR TECH RES ASSOCIATES INC CAMARILLOCA 93010

ISBN: (纸本)0819415340

During 1993, a series of experiments were performed under the advanced Research Projects Agency (ARPA) sponsorship using the SRI ultra-wide band UHF synthetic aperture radar (SAR). These experiments were performed over a variety of clutter backgrounds to assess the foliage penetration capability of the technology and to investigate target detection in clutter. Experiments were conducted observing tropical rain forest backgrounds in Panama, several different desert backgrounds in the Yuma vicinity, and the mid-latitude temperate forest of Maine. SAR images were formed from the raw data using Differential GPS to aid in the focusing. The three locations represent different levels of foliage cover, ranging from the sparsely vegetated desert sites to the triple canopied rain forest. The characteristics of each site are discussed first through a presentation of photography and SAR imagery. The clutter characteristics are studied through a comparison of the cumulative distributions, which are plotted using a variety of conventions. For each case, at least one reference target is included in the test scene. The signal of that target as processed by a common algorithm will be compared to the processed clutter distribution.

conference on Digital Video Compression on Personal Computers: algorithms and Technologies

作者： LEE, W GOLSTON, J GOVE, RJ KIM, YM UNIV WASHINGTON DEPT ELECT ENGNIMAGE COMP SYST LABSEATTLEWA 98195

ISBN: (纸本)0819414824

We present a software implementation of a real-time MPEG video codec on the MediaStation 5000 multimedia system. Unlike other compression systems whose sole function is the encoding or decoding of video data, the MediaStation 5000 is capable of performing various real-time operations involving a wide range of multimedia data, including image, graphics, video, and even audio. This programmability is provided by Texas Instruments TMS320C80, better known as Multimedia Video Processor (MVP), which is a single-chip multiprocessing device with highly parallel internal architecture. The MVP integrates a RISC processor, four DSP-like processors, an intelligent DMA controller, video controllers, and a large amount of SRAMs onto a single chip. Since the MVP contains such a high degree of parallel features, developing the MPEG software and mapping it to the MVP requires a thorough study of the algorithms and a good understanding of the processor architecture. By exploiting the advanced features of the MVP, the MediaStation 5000 can achieve the MPEG compression and decompression of video sequences in real time.

conference on algorithms for Synthetic Aperture Radar Imagery

作者： SHAW, SW SRI INT MENLO PKCA 94025

Ultrawideband (UWB) SAR images often contain clutter and other types of spatially correlated noise. To reduce these effects, we have developed a complex, multichannel, autoregressive image- modeling and inverse-filtering algorithm. Our algorithm extends a previously reported technique to include complex image data and a solution to the directionality problem of 2D AR models. A multichannel image pixel, represented by a vector, is modeled as an autoregressive process with a nonsymmetric half-plane (NSHP) support region. The parameters of this NSHP AR model, represented as matrices, are estimated by minimizing a squared residual. To account for possible nonstationarity in the image statistics, the estimation is performed over a series of small subwindows, which lends a degree of adaptabtility to the algorithm. Once estimates of the complex AR parameter matrices are obtained, they are used in an inverse filter. To account for the directionality inherent in the NSHP filter, we have adopted a bi-directional filtering approach, with the results of the two filters combined such that targets are enhanced and clutter is minimized. This algorithm has been applied to various UWB SAR images and shown to be an effective whitening filter. The resulting signal-to-clutter enhancement depends on a variety of factors, including clutter statistics, target size, and AR model order. A version of the whitening algorithm has been incorporated into our standard set of tools for processing UWB SAR images.

Multidimensional Synchronous Dataflow is a model of computation where functional blocks produce and consume data on a multidimensional index space. The model can express multidimensional signal processing systems and algorithms elegantly, and is able to reveal the data parallelism ofsuch systems in a way that raises possibilitiesfor better multiprocessor scheduling. We have formalized definitions and specijications for a two-dimensional model and have created a single-processor simulation domain in Ptolemy[l]. Our paper discusses the design issues and methodologies we used to eficiently handle the large amounts of two-dimensional data that the systems operate upon, The primary structures used were matrices to act as buffersand submatrices to access subsets of those buflers. © 1995 IEEE.

International conference on Acoustics, Speech, and signal processing (ICASSP)

作者： P. Monta Shiufun Cheung Advanced Television and Signal Processing Group Research Laboratory of Electronics Massachusetts Institute of Technology Cambridge MA USA

We describe a perceptual audio coder that employs nonuniform hierarchical filterbanks and entropy-coded lattice vector quantization. The nonuniform filterbanks present a good match to critical-band sampling, and they avoid the complications of block-size adjustment during signal transients. An entropy-coded lattice vector quantizer provides efficient quantization and coding of the filterbank samples. The coder achieves "transparent" quality at a rate of 96 kb/s, and efficient algorithms exist for the filterbank and vector quantizer subsystems.< >

Efficient techniques for speech compression are of practical interest. In this paper, a new compression algorithm based on Discrete Orthogonal Laguerre Functions (DOLFs) is proposed and analysed. Experimental results show that a good quality of the synthesized speech with a low bit rate representation is possible with a finite number of DOLFs basis.< >

In typical MC-DCT compression algorithms, up to 90% of the available bit rate is used to encode the location and amplitude information of the nonzero quantized DCT coefficients. Therefore, efficient encoding of the location and amplitude information is extremely important for high quality video compression. In this paper we describe the position-dependent encoding (PDE) approach for encoding the DCT coefficients. This method attempts to exploit the inherent differences in statistical properties of the run-lengths and amplitudes as a function of position. This paper includes preliminary comparisons between the PDE scheme and conventional coding approaches. The PDE approach can be applied in any transform/subband filtering scheme for image or video compression.< >

The electro-optical space surveillance (EOSS) technology program at MIT/Lincoln Laboratory develops advanced electro-optical technology for space and missile surveillance. This advanced technology includes visible CCD focal plane arrays and cameras, mid-wave IR (MWIR) Shottky barrier focal planes and cameras, and the detection processing algorithms and processors to optimize the use of these focal plane arrays. Some of these EOSS technologies are highly suited to the detection of faint near earth objects. A near-earth asteroid surveillance system has been designed to utilize recently developed technology and existing telescopes to meet the performance requirements outlined in the NASA SPACEGUARD Study (Morrison, 1992). A detailed model was developed to evaluate the expected detection performance of this system and the proposed Spaceguard system. The components of the designed system have been tested as part of routine device evaluation and field measurements. Results indicate that the proposed system can meet the performance objectives spelled out in the spaceguard study at lower cost and risk than the proposed spaceguard system and with existing technology.

Multipath fading is one of the major practical concerns in wireless communications. Multipath problem always exists in the mobile environment, especially for a mobile unit which is often embedded in its surroundings. The RAKE receiver has been used to reduce the multipath fading in a wideband spread spectrum mobile system. However, the tap weights of the multipath channel model need to be estimated. We explore the possibility of using advanced signal processing algorithms to estimate the multipath channels and propose a least-squares approach to tap weight estimation based on chip rate channel estimates to investigate the performance of the RAKE receiver in a realistic mobile environment. Simulations show that the new approach outperforms the existing approaches.< >
