摘要： The present invention relates to deblocking filtering, which may be advantageously applied for block-wise encoding and decoding of image or video signal. In particular, the present invention relates to performing an efficient and accurate decision on whether or not to apply deblocking filtering on an image block. The efficient and accurate decision is achieved by performing individual decisions on whether or not to apply deblocking filtering for segments of a boundary between adjacent image blocks, wherein the individual decision are based on pixels comprised in a subset of the pixel lines that the image blocks are composed of.

摘要： The present invention has been conceived to solve the previously described problems, and provides a texture representation method without any unnatural feeling while performing data compression equivalent to a conventional data compression or more. An input signal is separated in two frequency domains. The low-frequency component is faithfully coded by a conventional image/video coding apparatus. The high-frequency component is analyzed to compute representative texture parameters. Instead of faithfully coding the high-frequency component, only the computed texture parameters are stored or transmitted to a decoding apparatus. Then, the low-frequency component is reconstructed, whereas the high-frequency component is replaced by a natural texture that has been synthesized according to the texture parameters. The reconstructed low-frequency component and the synthesized high-frequency component are merged to generate an output signal.

摘要： In the case of a method for transformation encoding of moving-image sequences, motion vectors are estimated block-by-block, with which said motion vectors a motion compensation is carried out. The prediction error is transformation-encoded. According to the invention, the block size of the transformation encoding is coupled to the block size used in each case for the motion compensation. This measure makes it possible to enhance the efficiency of the encoding of the prediction error in hybrid encoding procedures that use various block sizes.

摘要： The present invention relates to a simplified pipeline for Sample Adaptive Offset (SAO) and Adaptive Loop Filtering (ALF) in the in-loop decoding of a video encoder and a video decoder. According to the present invention, filter parameter setting regions and filtering processing windows are aligned, to reduce the required amount of memory for parameter sets necessary for delayed filtering. This is preferably achieved by a displacement of the filter parameter setting regions with respect to LCU boundaries in at least one (preferably: vertical) or both vertical and horizontal directions.

摘要： Provided is an image coding method for performing intra prediction achieving higher coding efficiency. The method for coding image data on a block-by-block basis includes: generating a predicted block by predicting a current block; computing a difference between the current block and the predicted block; coding the difference computed in the computing; decoding the difference coded in the coding; and adding the difference decoded in the decoding to the predicted block to generate a decoded block, wherein the generating includes: detecting an edge in a previously decoded block corresponding to a block adjacent to the current block; and extrapolating or interpolating previously decoded image data corresponding to a pixel included in the block adjacent to the current block, along a direction of the edge detected in the detecting to generate the predicted block.
