摘要： The invention relates to a method for encoding a plurality of non overlapping blocks in a picture. The method comprises the steps of: transforming each of the blocks into a transformed block of coefficients in the frequency domain by applying a predefined transform; scanning the coefficients of at least two neighboring transformed blocks jointly from the lowest frequency to the highest frequency according to a predefined scanning pattern, the group of at least two neighboring transformed blocks being called super-block; and entropy coding the scanned coefficients of the super-block into an entropy coded group of bits.

摘要： The invention relates to a method for generating a saliency map for a picture of a sequence of pictures, the picture being divided in blocks of pixels. The method comprises a step for computing a saliency value for each block of the picture. According to the invention, the saliency value equals the self information of the block, the self information depending on the spatial and temporal contexts of the block.

摘要： The invention relates to a video encoding and decoding technical field of the signal processing, especially relates to a method for video clip assisted by clip identifier. The method defines a clip identifier on the video encoding and decoding rule as an identifier used specially for video stream clip. If the encoded video bit stream is clipped, then said clip identifier is inserted to the bit stream or used to replace the original identifier which functions as a start flag. The clip of the video bit stream can be operated conveniently by the invention. The features of the invention are: the bits, which mark whether the clipped video bit stream may be decoded and displayed incorrectly or not, are not required to appear in the unclipped bit stream; if it clips at a certain point of the bit stream, then said identifier will appear at this point to indicate that a problem in which the picture can not be decoded normally due to the predictive reference data being clipped may appear.
