摘要： The invention relates to video coding with inter-view prediction. A reconstructed depth map of a reference view is obtained, quantized according to a predetermined reference quantization. A reduced range information is obtained, wherein the reduced range information defines a reduced range of depth quantization levels available for the inter-view prediction within the range of quantization levels defined by the predetermined reference quantization. The distance information corresponding to the reduced range of depth quantization levels is enhanced by an adaptation function, which is defined based on the reduced range. The enhanced distance information is used for inter-view prediction, leading to improved coding efficiency.

摘要： The invention relates to a decoding apparatus for decoding a video coding block. The decoding apparatus comprises a decoding unit decoding the video coding block for providing a residual video coding block; a partitioning unit partitioning the video coding block on the basis of the coding information into two or more segments including a first segment and a second segment. The coding information comprises a first segment motion vector associated with the first segment of the video coding block and a second segment motion vector associated with the second segment of the video coding block. An inter prediction unit determines on the basis of the first segment motion vector a co-located first segment in a first reference frame and on the basis of the second segment motion vector a co-located second segment in a second reference frame and generates a predicted video coding block on the basis of the co-located first segment and the co-located second segment. The predicted video coding block comprises a predicted first segment and a predicted second segment. A motion-dependent filtering unit determines a divergence measure on the basis of the first segment motion vector and the second segment motion vector and applies depending on the divergence measure a first filter or a second filter to the predicted video coding block. A reconstruction unit reconstructs the video coding block on the basis of the filtered predicted video coding block and the residual video coding block.
