Abstract

In traditional compression standard quality assessment, compressor parameters and performance measures are the main experimental variables. In this paper, we show that the image content is an equally crucial variable which still remains unused. We compare JPEG, JPEG2000 and a proprietary JPEG2000 on four visually different datasets. We base our comparison on PSNR, SSIM, time and bits rate measures. This approach reveals that the JPEG2000 vs. JPEG comparison strongly depends on compressed images visual content.
