Verification of JPEG2000 encoder based on rate and distortion curve analysis

Article presents a methodology of JPEG2000 compression system verification based on a rate and distortion curve analysis. In the paper issues of subjective and objective image quality metrics are discussed, with special focus on “full-reference” methods. Authors propose division of the test images, into several groups, of similar spatial frequency content and the same resolution. Performed experiments revealed normal distribution of PSNR and deltaPSNR random variables, defined for reconstructed images. The elaborated methodology takes advantage of the normal distribution´s three-sigma rule to smart classification of failed tests.
