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 of the set of images, the hidden image comprising a source pixel area; dividing the current image into blocks for an encoding of the blocks of the current image according to an encoding sequence; and for a block of the target pixel area of the current image: 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.

Abstract: A method of processing an image, wherein the image is divided into a plurality of blocks is provided, which comprises, for a block of the plurality of blocks: determine prediction residual data representing prediction encoding data for pixels of the block; determine coefficients based on the prediction residual data; based on a number of non-null coefficients among the coefficients, the number of non-null coefficients being at least one, determine a processing to be performed on the prediction residual data for generating a binary flow of encoded pixels of the block.
