Embedded image coding using zerotrees of wavelet coefficients

IEEE Transactions on Signal Processing, 1993
The embedded zerotree wavelet algorithm (EZW) is a simple, yet remarkably effective, image compression algorithm, having the property that the bits in the bit stream are generated in order of importance, yielding a fully embedded code.

The wavelet transform, time-frequency localization and signal analysis

IEEE Transactions on Information Theory, 1990
Two different procedures for effecting a frequency analysis of a time-dependent signal locally in time are studied. The first procedure is the short-time or windowed Fourier transform; the second is the wavelet transform, in which high-frequency ...

Image coding using wavelet transform

IEEE Transactions on Image Processing, 1992
A scheme for image compression that takes into account psychovisual features both in the space and frequency domains is proposed. This method involves two steps.

Wavelets and T-pulses

Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 1995
Summary form only given, as follows. One attractive application of the wavelet is as a basis function that is of compact support both in the original and in the transform domain. However, this is not possible from a theoretical point of view. Namely, a pulse that is limited in time cannot simultaneously be limited in frequency.

Adaptive Wavelet Domain Filter for Versatile Video Coding (VVC)

Data Compression Conference, 2019
Owing to the ability of removing compression artifacts, extensive in-loop filters have been proposed for video coding standards. They are performed after the reconstruction of all coding units (CUs), however, none of them has been taken into account in ...
