Method and apparatus for compression using reversible wavelet transforms and an embedded codestream
TL;DR: In this paper, a reversible wavelet filter is used to generate coefficients from input data, such as image data, and an entropy coder performs entropy coding on the embedded codestream to produce the compressed data stream.

A new approach to recursive mirror filters with a special application in subband coding of images
TL;DR: The present method has looser filter constraints than previous recursive quadrature mirror filter (QMF) techniques, but may in certain applications require a large memory.

Vector DPCM image coding method and apparatus
TL;DR: In this paper, the authors proposed a method for encoding a graphics image by treating the image as plurality of cells, where each cell comprises a plurality of pixels and the states of the pixels of a cell are predicted using pixel states of priorly processed adjacent cells.
