9-3 Optimization of Lifting Coefficients for Lossless Image Coding

Abstract

This paper proposes a novel method for optimizing a lifting type of reversible wavelet transform for lossless image coding. Lifting coefficients are optimized for each image so that the amount of information on wavelet coefficients can have a minimum. Simulation results indicate that a coding rate decreases by about 0.03 bits/pel by applying the above coefficients to JPEG2000.
