An optimization-based method is proposed for the design of high-performance separable wavelet filter banks for image coding. This method yields linear-phase perfect-reconstructio...
—The JPEG 2000 image coding standard employs the biorthogonal 9/7 wavelet for lossy compression. The performance of hardware implementation of 9/7-filter bank depends on accuracy...
It has been observed that filter banks from a certain popular separable 2D wavelet class always appear to have a higher coding gain with respect to a separable image model than wi...
The design of a class of wavelet filters and its application in Scalable Video Coding (SVC) is discussed in detail in this paper. The design method uses maximal flat wavelet filte...
We develop a novel measure of joint time-frequency localization applicable to equivalence classes of finite-length discrete signals, which are of increasing importance in modern ...
