2014 16th IEEE International Workshop on Multimedia Signal Processing, MMSP 2014
作者: Weerakkody, Rajitha Mrak, Marta BBC Research and Development London United Kingdom
For video compression, the RGB signals are usually converted at the source to a perceptual colour space, followed by chroma sub-sampling, for coding efficiency. This is based on the typically higher human visual syste... 详细信息
