【Abstract】 This paper studies the evaluation methods for image compression algorithms and proposes test methods for compression algo- rithms including horizontal comparison test and vertical decomposition test. On the base of this, we design and realize a testing and analyzing tool for performance of image compression algorithms. This tool can test and analyze compression algorithms and generate kinds of analysis chart automatically, provides a lot of convenience for users and has very important practical value. In order to im- prove efficiency, veracity and perfectibility of the tool, this paper presents selection method for test images and analysis method for test results which have certain theoretical meaning.更多还原
