Error Inhomogeneity of Wavelet Image Compression
Despite the popularity of wavelet-based image compression, its error inhomogeneity - the error that is different for even and odd pixel locations, has not been previously analyzed...

Quality Constrained Compression Using DWT-Based Image Quality Metric
A quality constrained compression algorithm based on Discrete Wavelet Transform (DWT) is proposed. The spatial-frequency decomposition property of DWT provides possibility for not...

A Rate-Distortion Approach to Wavelet-Based Encoding of Predictive Error Frames
In this paper, we develop a framework for efficiently encoding predictive error frames (PEF) as part of a rate scalable, wavelet-based video compression algorithm. We investigate ...

Finite Precision Wavelets for Image Coding: Lossy and Lossless Compression Performance Evaluation
This paper investigates the robustness of the wavelet transform, implemented by means of the Lifting Scheme (LS), with respect to numerical errors in the representation and calcul...
