Adaptation to nonstationarity of embedded wavelet code stream
Abstract
We address a problem that affects the performance of all embedded wavelet image codecs-how to track time varying statistics of the coefficient code stream. We propose a family of techniques for rapid adaptation of arithmetic coding to changing statistics of the wavelet coefficients. These techniques improve the compression performance of existing wavelet image codecs, particularly at high bit rates and for lossless coding.
