چکیده
SeiMiyake NHK Science and Technical Research Laboratories 1-10-11. Kinuta. Setagaya Tokyo 157 • Japan To achieve high-rate image data compression while maintainig a high quality reconstructed image, a good image model and an efficient way to represent the specific data of each image must be introduced. Based on the physiological knowledge of multi channel characteristics and inhibitory interactions between them in the human visual system, a mathematically coherent parallel architecture for image data compression which utilizes the Markov random field Image model and interactions between a vast number of filter banks, is proposed.

متن کاملAdaptive filter banks for lossless image compression
A subband decomposition based lossless image compression algorithm based on adaptive is described. The decomposition is achieved by a two-channel adaptive filter bank. The resulting coefficients are lossy coded first, and th en the residual error between the lossy and error free coefficients are compressed. The locations and the magnitudes of the nonzero coefficients are encoded separately by a...
متن کاملW Performance Evaluation of Biorthogonal Filters using Adaptive Synthesis Filter Banks for Image Compression
This paper evaluates the performance of various biorthogonal filters using adaptive synthesis filter banks for image compression. The adaptive synthesis filter banks are used to exploit the phase diversity of synthesis filters in subband coding system. Odd length biorthogonal filters are used because even length filters exhibit fractional delay in compression. It is shown that adaptive synthesi...
