This disclosure describes intra-smoothing techniques for intra-coding of video data. In one example, a video encoder is configured to determine a plurality of prediction samples for intra-predictive coding of a block to be coded in a video frame, calculate a local statistic for a first prediction sample of the prediction samples, select a filter from a plurality of filters based on the local statistic, and apply the selected filter to the first prediction sample. The video encoder may also be configured to calculate at least one local statistic for each prediction sample of the prediction samples, select a filter from a plurality of different filters based on the at least one local statistic for each prediction sample, and apply each selected filter to the corresponding prediction sample to generate the filtered version of the prediction sample. Embodiments further include video decoders and method of decoding encoded video signals. |
