摘要： The present disclosure relates to encoding a decoding video employing texture coding. In particular, a texture region is identified within a video picture and a texture patch is determined for said region. Clustering is performed to identify a texture region within the video image. The clustering is further refined. In particular, one or more brightness parameters of a polynomial is determined by fitting the polynomial to the identified texture region. In the identified texture region, samples are detected with a distance to the fitted polynomial exceeding a first threshold and identify a refined texture region as the texture region excluding one or more of the detected samples. Finally, the refined texture region is encoded separately from portions of the video image not belonging to the refined texture region.

摘要： The present disclosure relates to encoding a decoding video employing texture coding. In particular, a texture region is identified within a video picture and a texture patch is determined for said region. Moreover, a first set of parameters is derived specifying weighting factors for reconstructing spectral coefficients of the texture region by fitting the texture region in spectral domain to a first function of the texture patch, the first function being defined by the first set of parameters. The texture patch and the first set of parameters are then included into a bitstream which is output of the encoder and provided in this way to the decoder which reconstructs the texture based on the patch and the function applied to the patch.

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.
