TL;DR: This paper analyzes the effect of a scalar uniform quantization in an adaptive multiresolution analysis based on a lifting implementation and provides conditions for recovering the original decisions at synthesis.
Abstract: In this paper we investigate the potential of a special class of adaptive wavelet schemes to yield an effective representation for compression purposes. In particular, we analyze the effect of a scalar uniform quantization in an adaptive multiresolution analysis based on a lifting implementation. We provide conditions for recovering the original decisions at synthesis and we provide expressions that relate the reconstruction error to the quantization error. Such an analysis is essential for the application of our adaptive decompositions in lossy image compression algorithms.
