*Compression ratio and PSNR values are averaged over five bands of each scene.
**Average values are calculated over all images, except scenes 1 and 2. Due to the small set of scenes and the high compression ratio on scenes 1 and 2, their values were not considered to avoid distorted average values for some algorithms.
