Abstract:
A method for disoccluded region coding in multiview video data stream by an entropy encoder, the method comprising the steps of: coding a block of a base view; storing state and estimated probabilities in contexts models of the entropy encoder in a context storage module with a reference identifying the block of the base view; repeating the aforementioned steps of coding and storing for every block of the base view of the multiview video data stream; starting coding of a disoccluded region and dividing, into blocks, disoccluded area of a side view associated with the base view; determining, for neighboring blocks, of currently coded block, that have not been in the disoccluded area, a corresponding block in the base view, using a block correspondence database; when such a correspondence is determined, reading a previously stored state and estimated probabilities in context models of the entropy encoder for the corresponding block; copying all coding modes from the corresponding block to the neighboring block; applying state and estimated probabilities in context models to the entropy encoder of the block that is adjacent to the currently processed block; encoding, by the entropy encoder, the selected block of the side view; and repeating steps (e) to (i) for all blocks of the side view associated with the base view processed in steps (a) to (b).
