摘要： A method of adaptiveiy encoding and decoding frames of video data is disclosed. Luma and chroma colour components of each frame of video data are divided into macroblocks, wherein each macroblock comprises at least one block. At least two candidate coding schemes are provided for each macroblock. A first candidate coding scheme applies a motion vector for each block in the luma component of the data to all luma and chroma components of the data. A first rate-distortion cost measure is calculated for the first candidate coding scheme that is representative of both the distortion of the original video data introduced by the first coding scheme and the bit rate required to support the first coding scheme. A second candidate coding scheme applies a motion vector to each block of a luma component of the data and further applies a separate motion vector for each block in a chroma component of the data. A second rate-distortion cost measure is then calculated for the second candidate coding scheme that is representative of both the distortion of the original data introduced by the second coding scheme and the bit rate required to support the second coding scheme. For each macroblock, the candidate coding scheme with the lowest rate-distortion cost measure is then selected. The coding scheme is therefore advantageously adapted in accordance with bit rate and distortion requirements.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for representing an image group. SOLUTION: In this method, a group of images is clustered in a color domain, and the center of gravity of the obtained cluster is determined as a dominant color value (one or more values). A dominant color representation expressing the group of images in terms of the dominant color values (one or more values) is derived for the dominant color value (one or more values). A component of the color representation includes dispersion of color distribution, weight indicating color effect, the number of dominant colors, and spatial uniformity of pixels corresponding to the dominant color.

摘要： In a generalised hypothetical reference decoder, an encoder provides an encoded video bitstream, using scalable video coding, which may be subject to bitstream rewriting. Bitstream rewriting enables the bitstream to be decoded by devices not compatible with scalable video coding e.g. legacy devices. The encoder further determines a set of parameters for use by a decoder in the event of bitstream rewriting to ensure effective decoding of the video bitstream by the decoder. The set of parameters is introduced in the encoded video bitstream.
