1. A method for processing a current image of a set of images, the method comprising, 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 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,
wherein the hidden image and the current image are images of the set of images of a video sequence to be encoded according to a video encoding scheme,
the method further comprising:
obtaining metadata defining the target pixel area in the current image, wherein the obtained metadata indicates that the hidden image included in the encoded video sequence is usable to customize the current image, and
including the metadata in metadata describing the encoded video sequence.
