摘要： A method of and an apparatus for encoding and decoding using transformation bases of a yet higher efficiency. In a method for encoding an object signal in compliance with a transformation rule, a signal correlating to the object signal is obtained, and a transformation base that forms the transformation rule is derived based on a characteristic of the obtained reference signal. The object signal is transformed and encoded in compliance with the transformation rule based on the derived transformation base. Accordingly, the object signal is transformed in compliance with the transformation rule based on the transformation base derived from the characteristic of the reference signal. Since the reference signal is correlated to the object signal, the transformation base derived from the characteristic matches the feature of the object signal.

摘要： An input image signal 101 is divided into MC block units and, when coding processing is performed in these divided units, a motion compensation section 107 generates a motion-compensated prediction image 106a by detecting movement amounts in predetermined MC block units, a smoothing filter section 124 performs, with respect to the prediction image 106a, smoothing of pixels located at the boundaries of adjoining MC blocks on the basis of predetermined evaluation criteria, and a prediction residual signal 108, which is obtained from the difference between the prediction image 106b obtained by the smoothing, and the input image (input image signal 101), is encoded. Accordingly, it is possible to use relatively straightforward computation to perform processing, with respect to a prediction frame image generated by block-unit motion-compensated interframe prediction (MC), to adaptively smooth a discontinuous waveform generated between MC blocks of the prediction frame image, whereby the efficiency of low bit rate coding that employs interframe MC is improved.

摘要： A method and an apparatus improving the coding efficiency by representing encoded data in a compact form by means of a pattern matching technique. A waveform vector similar to a partial signal waveform of an image signal in a predetermined group of waveform vectors is searched for. When a compression encoding is performed for information to identify the waveform vector searched for, similarity information, and a position in an image signal of the partial signal waveform in accordance with a predetermined encoding rule, the position in the image signal of the partial signal waveform is encoded through replacement with position information in a predetermined partial domain of the image signal. As a result, since the position in the image of the partial signal waveform that is the most similar to the waveform vector is encoded through replacement with the position information in the predetermined partial domain of the image signal, it is possible to represent the position more compactly.
