Abstract
A method for processing a current image of a set of images is proposed, which comprises, at a video processing device comprising a processor: determining a target pixel area in the current image; obtaining a hidden image, comprising a source pixel area, of the set of images; dividing the current image into blocks for an encoding of the blocks according to an encoding sequence; and for a block of the target pixel area: determining a motion vector pointing to a block of the source pixel area in the hidden image corresponding to the block of the target pixel area, and based on the motion vector, encoding the block of the target pixel area according to a temporal correlation prediction mode pursuant to which no pixel residual representing a difference between the block of the target pixel area and the corresponding block of the source pixel area is generated.
