Affine Linear Weighted Intra Predictions
Abstract: There are disclosed techniques for block wise encoding and decoding. The techniques may be applied to encoders, decoders, and methods for encoding and/or decoding. In one example, there is disclosed a decoder (54) for decoding a picture (10) from a data stream (12, 80). The decoder may be configured to predict a predetermined block (18) of the picture (10) by mapping a set of P neighboring samples (17'c, 17'a) neighboring the predetermined block (18) using a linear or affine linear transformation (17M) onto a set of Q predicted values for samples of the predetermined block (18). The linear or affine linear transformation (17M) may comprise P*Q weighting factors among which at least ¼ P*Q weighting factors are non-zero weighting values, which comprise, for each of the Q predicted values, a series of P weighting factors relating to the respective predicted value, wherein the series, when being arranged one below the other according to a raster scan order among the samples of the predetermined block (18), form an envelope which is omnidirectionally non- linear.
