Abstract (en)
[origin: WO2019072918A1] Predictor for intra predicting a predicted block for a currently processed block of a picture from reference samples in a two-dimensional coordinate system which are derived from one or more previously processed blocks of the picture, the predictor comprising: an arranger configured for arranging the reference samples as a one-dimensional reference sample sequence in a one-dimensional coordinate system; a smoothing filter configured for filtering the one-dimensional reference sample sequence based on a bilateral filter function with a one-dimensional window in order to obtain a one-dimensional filtered reference sample sequence comprising filtered reference samples; and a determiner configured for determining for each of a plurality of predicted image samples of the currently processed block a respective prediction value by using the filtered reference sample sequence in order to produce the predicted block.
