Abstract:
1. Reconstruction method of picture, called current picture, being part of a sequence of pictures, from coded digital data representative of said current picture which is divided into blocks of pixels, said method comprising the following steps: construct, for each current picture block, a first predictive block from a first picture and a second picture from said sequence previously reconstructed, construct, for each current picture block, a second predictive block from said first picture and said second picture, calculate, for each current picture block, a value, called confidence value, representative of the proximity between the visual content of the first predictive block and the visual content of the second predictive block, and reconstruct each current picture block from a part of said coded digital data representative of said current picture block and from first auxiliary data calculated from the first and second predictive blocks when the confidence value of said block is greater than a predetermined threshold.
