Path-based encoding efficiency of wavelet-based compressed imagery

Abstract

This paper presents a method for testing the performance of different path-based coders of wavelet transformed imagery. Path-based coders are very popular techniques for compressing wavelet-transformed imagery, but there has been little knowledge formally documented on the most efficient method of path traversal for the coding process. Thus, this paper presents the findings of several performance tests using two path-based coding techniques. These techniques are used to independently code each subband of several wavelet transformed images using different coding paths in each test. The results are documented and give rise to conclusions on how to best traverse each subband in a wavelet-transformed image for most efficient coding
