Patent ID: 8588292

Claim:
A method for decoding a signal representative of an image sequence, wherein the method comprises the following steps: extracting motion tubes from said signal with a decoding device, each motion tube comprising a block of pixels capable of evolving independently of at least one other motion tube, two motion tubes possibly, at a given instant, allocating different values to one and the same pixel of one of said images, each of said motion 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 delimiting a period of time over at least three images for at least one motion tube of said motion tubes; transition information cues, enabling said reference block to be updated at at least one instant t of said sequence; so that at least one of said motion tubes corresponds to a block of pixels evolving over a course of a time period delimited by said start-of-tube and end-of-tube instants over at least three images; processing said transition information cues, delivering a current block for each of said motion tubes in a current image at an instant t; combining the information cues associated with the current blocks of at least two of said motion tubes capable of evolving independently of each other over at least the three images and overlapping in an overlap zone of said current image, so as to reconstruct pixels which are optimized in said overlap zone.
