Abstract
Methods and apparatus are provided for video encoding and decoding using a motion matrix. An apparatus includes a video encoder for encoding a picture in a video sequence using a motion matrix. The motion matrix has a rank below a given threshold and a sparse representation with respect to a dictionary. The dictionary includes a set of atoms and basis vectors for representing the picture and for permitting the picture to be derived at a corresponding decoder using only the set. The dictionary formed from a set of reference pictures in the video sequence.
