METHOD AND DEVICES FOR CODING AND DECODING AN IMAGE SEQUENCE REPRESENTED WITH THE AID OF MOTION TUBES, CORRESPONDING COMPUTER PROGRAM PRODUCTS AND SIGNAL

摘要

A method and apparatus are provided for decoding a signal representative of an image sequence. The method includes extracting motion tubes from the signal, each of the tubes being defined by at least the following information cues: a block of reference pixels comprising reference texture information cues; start-of-tube and end-of-tube instants; and transition information cues. The method further includes processing the transition information cues and combining the information cues associated with the current blocks of at least two of the tubes overlapping in an overlap zone of the current image.
