Spherical Coding Algorithm for Wavelet Image Compression
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009-05)
In recent literature, there exist many high-performance wavelet coders that use different spatially adaptive coding techniques in order to exploit the spatial energy compaction property of the wavelet transform. Two crucial ...
Equiripple design of real and complex filter banks
A simple methodology is presented for mapping minimax-optimal, equiripple unconstrained filters such as those produced by the Parks-McClellan algorithm to design equiripple perfect-reconstruction filter banks. The method ...
Wavelet image coding using the spherical representation
In this paper, we introduce the "spherical representation", which provides a new adaptive framework for modeling and coding the image information in wavelet subbands. Based on this representation, a practical coding algorithm ...
