W Performance Evaluation of Biorthogonal Filters using Adaptive Synthesis Filter Banks for Image Compression

چکیده
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 synthesis filters derived from higher order biorthogonal filters with higher degree of smoothness display significant objective improvements over lower order biorthogonal filters in image compression.

متن کاملSpace-Frequency Balance of Biorthogonal Wavelets
This paper shows how to design good biorthogonal FIR filters for wavelet image compression by balancing the space and frequency dispersions of analysis and synthesis lowpass filters. A quality metric is proposed which can be computed directly from the filter coefficients. By optimizing over the space of FIR filter coefficients, a filter bank can be found which minimizes the metric in about 60 s...

متن کاملDESIGN OF UNEQUAL−LENGTH LINEAR−PHASE FILTER BANKS WITHOUT REDUNDANCY (WedAmPO2)
In this paper, we present a new structure for linear−phase filter banks without redundancy, which have unequal−length filters at each subband. First, we extend the simplified lattice structure of the linear−phase filter bank to the unequal−length linear−phase paraunitary filter bank. In general, the unequal−length linear−phase paraunitary filter bank has equal−length filters at both the analysi...
