摘要： In a block-based motion compensated system, coding noises may arise due to lossy operations. Adaptive loop filter (ALF) is a technique used to improve the quality. A pixel adaptive (PA) ALF method was developed that uses the Sum-modified Laplacian Measure (SLM) to classify pixels and applies a respective ALF filter to each pixel according to the SLM. While the PA ALF achieves better performance over a conventional single filter (SF) based ALF, the PA ALF causes higher complexity and consumes more power due to the high complexity and per-pixel filter switching. Accordingly region based ALF scheme is disclosed which allows adaptive filter selection on a region by region basis and does not require per-pixel filter switching. In one embodiment according to the present invention, a picture is divided into M×N regions. The region based ALF also allows region merging for the M×N regions to improve performance. In another aspect of the present invention, the optimal ALF design also takes into consideration of the system complexity by using rate-distortion-complexity optimization (RDCO). The RDCO technique is also applied to sample adaptive offset (SAO) design.

摘要： In one embodiment, there is provided a moving image decoder for decoding a compression-coded moving image stream. The decoder includes: a deblocking filter configured to perform deblocking filter processing on each of frames to be decoded; a load detector configured to detect a magnitude of internal processing loads occurring inside a video player, including a processing load for decoding; a determination module configured to determine whether to bypass the deblocking filter processing, depending on the magnitude of the internal processing loads. The deblocking filter is configured to bypass the deblocking filter processing, if the magnitude of the internal processing loads is bigger than a threshold value and a processing subject block of the frame is decoded using inter-view prediction.

摘要： PROBLEM TO BE SOLVED: To provide a video decoding apparatus and a video decoding method that are able to bypass deblocking filtering by using inter-parallax prediction information.SOLUTION: The video decoding apparatus decodes a compression-coded video stream, and includes: deblocking means that performs deblocking filtering on each of frames to be decoded; load detecting means that detects the size of an in-apparatus processing load including a processing load necessary for decoding; and determining means that, in accordance with a load level representing the size of the in-apparatus processing load detected by the load detecting means, determines whether or not the deblocking filtering is to be performed. When it is determined on the basis of the determination result of the determining means that the load level is not less than a predetermined threshold value, the deblocking filtering means omits the deblocking filtering when a block of the frame to be processed is used for inter-parallax prediction.
