Display stream compression artifacts
WebMay 19, 2024 · "Visually lossless" has a stricter requirement. It is established by a "flicker" test or a "panning" test. The former is the accepted standard under ISO/IEC 29170-2 written by the JPEG. The latter is a proposal for addition used in an evaluation experiment for Display Stream Compression in DisplayPort. It is apparently more sensitive. Web15.6.4.1 Removal of Compression Artifacts. The problem of removing compression artifacts addresses the recovery of information lost due to the quantization of parameters during compression. More specifically, in the majority of existing image and video compression algorithms the image (or frame in an image sequence) is divided into …
