picture compression

picture compression

[′pik·chər kəm‚presh·ən]
(computer science)
The elimination of redundant information from a digital picture through the use of efficient encoding techniques in which frequently occurring gray levels or blocks of gray levels are represented by short codes and infrequently occurring ones by longer codes.

They cover digital picture compression and coding structure, vision modeling, coding artifacts and visual distortions, video quality testing, perceptual video quality metrics, the "philosophy of picture" quality scale, structural similarity based image quality assessment, vision model based impairment metrics, computational models, the no- reference quality metric for degraded and enhanced video, HVS based perpetual video encoders, perceptual image coding, foveated image and video coding, artifact reduction by post-processing in image compression, reduction of color bleeding in DCT block-coded video, error resilience for video coding service and critical issues and challenges.
So, supplementary technique of picture compression would be approved out as explicitly JPEG technique and Entropy coding etc.
