Title
(EN) VIDEO COMPRESSION
(FR) COMPRESSION VIDÉO
Abstract
(EN)
An example non-transitory computer-readable medium includes instructions. When executed by a processor, the instructions cause the processor to split a video frame into a first frame including blocks classified as natural and a second frame including blocks classified as artificial. The instructions also cause the processor to compress the first frame with a first compression technique. The instructions also cause the processor to compress the second frame with a second compression technique.
(FR)
Un support non transitoire lisible par ordinateur comprend, selon un exemple, des instructions. Lorsqu'elles sont exécutées par un processeur, les instructions amènent le processeur à diviser une trame vidéo en une première trame comprenant des blocs classés comme étant naturels et en une seconde trame comprenant des blocs classés comme étant artificiels. Les instructions amènent également le processeur à compresser la première trame à l'aide d'une première technique de compression. Les instructions amènent également le processeur à compresser la seconde trame à l'aide d'une seconde technique de compression.
