摘要： The invention is related to spatial diffusion in images. Spatial diffusion helps blurring small discontinuities. Edges become sharper by spatial diffusion as well.A method for generating a spatial diffused image from an input image is described wherein the method comprises applying on the input image an inverted Gaussian spatial bilateral filter with a spatial weight which takes the form of an inverted Gaussian.The inverted-Gaussian-spatial bilateral filter, which uses an inverted-Gaussian function as the kernel of spatial filter, can remove small spots in large smooth areas efficiently.

摘要： Video equipment, e.g. for TV producers studios, need to display multiple channels of bit-streams simultaneously. Decoding multiple streams of high bit-rate videos is extremely computational intensive. An improved method for browsing an encoded frequency domain video sequence comprises steps of determining a spatial and/or temporal reduction level for browsing a video sequence, determining according to the determined reduction level frames, fields or parts of blocks or macroblocks to be skipped for decoding, and decoding the remaining data to a video with lower spatial and/or temporal resolution. The reduction may include adaptive partial coefficient decoding, motion vector truncation and/or simplified deblocking filtering. The reduction of spatial resolution is advantageously performed in the frequency domain, so that the inverse quantization process and the iDCT processes require less computing.

摘要： The invention is related to a method for decoding an image frame of an image frame sequence and to a corresponding decoder. The method comprises the steps of reconstructing a representation of the image frame, classifying at least one block boundary as to be either high-freq or low-freq and filtering pixels of the at least one block boundary in dependency on the classification and outputting the filtered representation. Film grain noise and/or random texture are more likely to produce high-freq boundaries. Therefore, filtering boundary pixels in dependency on frequency classification helps preserving film grain noise and random texture which are of relevance for video quality at high bit rates.

摘要： Several attempts have been tried to improve the performance of intra-prediction in video encoding and decoding, which are targeting at pixel level parallelization. A solution for implementing an improved intra-prediction method on a parallel processing platform uses estimated predictors instead of reconstructed exact predictors. This enables faster estimation of predictors, and allows an encoder to perform intra-prediction for all blocks of at least a portion of an image simultaneously.

摘要： 3D models often have a large number of small to medium sized connected components, with small numbers of large triangles, often with arbitrary connectivity. The efficiency of compact representation of large multi-component 3D models can be improved by detecting and representing similarities between components thereof, even if the components are not exactly equal. The invention uses displacement maps for encoding two or more different but similar geometry patterns differentially, based on clustering and a cluster representative surface. A method for encoding a plurality of geometry patterns comprises detecting and encoding identical copies of geometrical patterns, detecting and clustering similar geometry patterns, and detecting partial similarity. The detecting partial similarity comprises generating a cluster representative surface, generating for at least one clustered geometry pattern a displacement map, and encoding the common surface and the displacement maps.
