Patent ID: 8774538

Claim:
Method of decoding a sequence of digital images encoded according to a predictive format, using encoded auxiliary data, the encoded auxiliary data being representative of at least part of said sequence of digital images, the method comprising: decoding a current encoded image received with at least one detected error, including applying an error concealment decoding on at least part of the current encoded image containing such a detected error to obtain a first decoded image, obtaining an item of information representative of reconstruction errors based upon a reconstruction confidence of the error concealment decoding for at least one pixel of the part of the current encoded image, processing the encoded auxiliary data and the first decoded image based upon the item of information representative of reconstruction errors to obtain corrected auxiliary data, and modifying the first decoded image to obtain a second decoded image based upon the corrected auxiliary data, wherein the item of information representative of errors is an error map including non-integer values associated with the first decoded image, comprising, for each pixel of the first decoded image, a real value P x,y representative of a probability of correct reconstruction associated to the decoded value of the pixel, such that: 0 ≦P x,y ≦1, wherein the current encoded image is encoded predictively with respect to a reference image according to a set of associated motion vectors, and wherein the step of obtaining of an item of information representative of reconstruction errors include obtaining a reference error map corresponding to the reference image, and propagating the reference error map according to the set of motion vectors to obtain a propagated error map, wherein the obtaining of an item of information representative of reconstruction errors further comprises combining the propagated error map with an error probability map comprising, for each pixel reconstructed by error concealment decoding, a value representative of a probability of correct reconstruction associated with the pixel.
