Comparison of JPEG Image Coders

By Sonja Grgic, Marta Mrak and Mislav Grgic


Abstract: 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 ratedistortion 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
