摘要
Methods and apparatuses for encoding and decoding video are disclosed. The method of encoding video includes assigning (12) a distortion versus quantization curve to a block in a picture of a video based on a perceptual metric classification of the block, determining a quantization parameter (132) for the block based on the distortion versus quantization curve and a target distortion for the block, the target distortion being an overall target distortion for the picture and encoding (16) the block based on the quantization parameter. A bitstream formatted to include encoded data, and computer-readable storage mediums and computer-readable program products for encoding and decoding video are also disclosed.
