1. An intra-prediction module for use in a video encoder that encodes a video signal including picture data, the intra-prediction module comprising: a candidate screening preprocessor configured to process blocks of the picture data based on intra-prediction candidate data corresponding to a plurality of pixels of the blocks, wherein the intra-prediction candidate data indicates a first subset selected from a plurality of intra-prediction partitions and a second subset selected from a plurality of intra-prediction modes, wherein the processing includes screening the intra-prediction candidate data to generate screened intra-prediction candidate data that indicates a third subset selected from the plurality of intra-prediction partitions and a fourth subset selected from the plurality of intra-prediction modes; and a final intra-prediction processor, coupled to the candidate screening preprocessor, that determines final intra-prediction data, based on the screened intra-prediction candidate data.
