| 释义 | compression A number of steps are involved in video compression, including filtering, color-space conversion, scaling, transforms, quantization and compaction, and interframe compression. Lossless compression enables faithful reproduction of the signal, with no data loss, although compression rates tend to be relatively low. Lossy compression tends to produce artifacts, which are unintended and unwanted distortions or aberrations that result in a degraded signal, but supports very high compression rates. Additional compression techniques include Modified Huffman (MH), Modified Read (MR), and Modified Modified Read (MMR). See also color-space conversion, filtering, interframe compression, lossless compression, lossy compression, Markov source, MH, MMR, Morse code, MR, quantization and compaction, run-length encoding, scaling, string coding, suppression, and transform. |
