Abstract
Encoding a video signal including pictures includes generating perceptual representations based on the pictures. Reference pictures are selected and motion vectors are generated based on the perceptual representations and the reference pictures. The motion vectors and pointers for the reference pictures are provided in an encoded video signal. Decoding may include receiving pointers for reference pictures and motion vectors based on perceptual representations of the reference pictures. The decoding of the pictures in the encoded video signal may include selecting reference pictures using the pointers and determining predicted pictures, based on the motion vectors and the selected reference pictures. The decoding may include generating reconstructed pictures from the predicted pictures and the residual pictures.
