摘要： The present invention relates to the field of picture processing. Especially, the invention deals with improving the deblocking filter of an image coding device. At most a number MA of sample values of the first image block adjacent to the block edge are modified and at most a number MB of sample values of the second image block adjacent to the block edge are modified; or at most a number MA of sample values of the second image block adjacent to the block edge are modified and at most a number MB of sample values of the first image block adjacent to the block edge are modified, MA ≠ MB.

摘要： A method of coding implemented by a coding apparatus. The method includes selecting an intra prediction mode for a current block, and encoding the selected intra prediction mode using truncated binary coding when the selected intra prediction mode is a remaining mode.

摘要： An image processing device (501) for use in an image encoder and/or an image decoder, for deblocking a block edge between a first block and a second block of an image encoded with a block code, is provided. The image processing device (501) comprises a filter (502) for filtering the block edge, configured to, for at least some of the pixels to be filtered, within a deblocking range from the block edge, the deblocking range being perpendicular to the block edge, determine a filtered pixel value from an original pixel value of the pixel and at least one further pixel value, determine a clipping value of the pixel, dependent upon a distance of the pixel from the block edge, and clip the filtered pixel value, using the clipping value resulting in a deblocked pixel value.

摘要： An apparatus and a method for filtering reconstructed images, in particular, video images, with adaptive multiplicative filters. The efficiency of the filtering operation is increased by restricting the allowable values of the filter coefficients to those that have only a limited number of "ones" in the binary representation.
