Abstract
The author addresses how regularity, frequency selectivity, and phase act upon the performance of a still image compression scheme using wavelet decomposition. Preliminary results are given for a simple compression scheme using orthonormal separable wavelet transforms, scalar quantization, rate/distortion optimization, various coding criteria, and a large number of \´wavelet\´ filters with balanced regularity, frequency selectivity, and phase. It is shown that regularity may be relevant for still image compression, at least for short filters (L>
