International Conference on Acoustics, Speech, and Signal processing (ICASSP)
作者: P. Kelly V. Algazi Signal and Image Processing Laboratory Department of Electrical and Computer Engineering University of California Davis CA USA
The emphasis of many algorithms that have been proposed for the compression of binary images has been the efficient coding of local redundancy in data. We propose that increased compression may be achieved by a decomp... 详细信息

computer VISION GRAPHICS AND IMAGE processing 1983年 第3期21卷 368-382页
作者: BURT, PJ Image Processing Laboratory Electrical Computer and Systems Engineering Department Rensselaer Polytechnic Institute Troy New York 12181
A common task in image analysis is that of measuring image properties within local windows. Often usefulness of these property estimates is determined by characteristics of the windows themselves. Critical factors inc... 详细信息

INTERNATIONAL JOURNAL OF ELECTRONICS 1983年 第4期55卷 533-549页
作者: SODERSTRAND, MA VIGIL, MC Department of Electrical and Computer Engineering Signal and Image Processing Laboratory University of California Davis CA 95616 United States Hewlett Packard Davis CA United States
A computer or microprocessor-based adaptive digital filter can easily be constructed to adapt structure as well as weights. These totally adaptive filters will always find a structure and set of weights which offer eq...

IEEE TRANSACTIONS ON COMMUNICATIONS 1982年 第5期30卷 1088-1094页
作者: ALGAZI, VR DEWITTE, JT Signal and Image Processing Laboratory Department of Electrical and Computer Engineering University of California Davis CA USA Department of Electrical and Computer Engineering University of California Davis CA USA
In this paper the authors derive simple approximate formulas for the performance of entropy-encoded DPCM for a Gaussian random process and a frequency-weighted mean-square distortion measure. Using these results they ... 详细信息

1982 IEEE International Conference on Acoustics, Speech, and Signal processing, ICASSP 1982
作者: Algazi, V. Ralph Fino, Bernard J. Department of Electrical and Computer Engineering Signal and Image Processing Laboratory University of California DavisCA95616 United States TRT 5 Avenue Reaunur B.P. 21 Le Plessis Robinson92350 France
For several signal processing applications, the usefulness of Fast Unitary Transforms (FUT) is now well recognized [1-7]. For signal representation, filtering and encoding, it is well known that the Karhunen-Loeve (KL... 详细信息

作者: A. Jain S. Ranganath Signal and Image Processing Laboratory Department of Electrical and Computer Engineering University of California Davis CA USA
In this paper, we consider application of 2-D stochastic models discussed in [1] to develop noncausal FIR filters for restoration of images degraded by additive white noise. The semicausal model of [1] is used to desi... 详细信息
