Comparison of JPEG Image Coders

In this paper we report results from our comparative study of JPEG and JPEG2000 image coders using two image quality measures: Peak Signal to Noise Ratio (PSNR) as traditional objective picture quality measure, and Picture Quality Scale as perception based quantitative picture quality measure. Coders are evaluated in rate-distortion sense. The influences of different image contents and compression ratios are assessed. The objective of this paper is to provide a quantitative and qualitative comparison of JPEG and JPEG2000 image coding focusing on low bitrates.
