    Abstract: A current video coding block of a frame of a video signal is intra predicted. The current video coding block comprises a plurality of pixels and each pixel is associated with a pixel value. On the basis of a plurality of primary reference pixel values a plurality of secondary reference pixel values are generated. The plurality of primary reference pixel values are associated with a plurality of primary reference pixels located in neighboring video coding blocks of the current video coding block. Each of the secondary reference pixel values is generated on the basis of two or more of the primary reference pixel values. The pixel values of the pixels of the current video coding block are intra predicted on the basis of the plurality of primary reference pixel values and the plurality of secondary reference pixel values.

    Abstract: A prediction technique, which use pre-prediction filtering techniques to reduce noise influence on the predicted samples of a block to be reconstructed, is presented. The prediction techniques suggested herein can be for example used in an encoding apparatus or a decoding apparatus. The reference samples that are used to reconstruct a given block of pixels of an image are categorized or segmented into subsets. The subsets may be processed differently, e.g. the subsets may be subjected to distinct filters. Examples of such filters include smoothing filters and/or deblocking filters, which are applied to the respective subsets of the reference samples.
