Abstract
In a video coding system, it is proposed to improve the intra prediction based on intra-block copy by allowing a decoder-side refinement allowing further refinement of the block vector obtained from IBC using a template matching process. In this template matching, the decoder searches in an iterative process the best match for the current block (L-shaped) template within the reconstructed area, adjacent to the block vector determined using the IBC 10 prediction. This technique allows to obtain a finer precision that what is possible with IBC while minimizing the amount of coding information. In at least one embodiment where a coarse precision is used for IBC, it allows at the same time to benefit from significant coding gain provided by IBC while providing a much finer precision with reduced signaling of the block vector.
