Skipping Selected Steps of DWT Computation in Lossless JPEG 2000 for Improved Bitrates
Roman Starosolski
In order to improve bitrates of lossless JPEG 2000, we propose to modify the discrete wavelet transform (DWT) by skipping selected steps of its computation. We employ a heuristic t…

Reversible Denoising and Lifting Based Color Component Transformation for Lossless Image Compression
Roman Starosolski
An undesirable side effect of reversible color space transformation, which consists of lifting steps (LSs), is that while removing correlation it contaminates transformed component…
