摘要:
An apparatus and method for spatial encoding of intra-predictions for a current block of a video sequence without the need to average across a number of best template matches. The encoder identifies and sorts the best template matches for the current block within previously coded and reconstructed blocks which neighbor the current block of video. In response to determining actual predictive error for the sorted list of matches, a selector is generated identifying which of the sorted templates is optimal. The selector is then communicated for receipt by the decoder, which is adapted for performing the same template matching and sorting, which is followed by selection of the optimum candidate in response to using the selector. In response to the selector information the decoder can provide optimum template matching without the compromise or overhead of taking averages across the best template candidates.
