Abstract: Variable-length encoder 16 feeds a CBP as an input symbol H1 to variable-length code output part 30. Coded symbol memory 31 supplies CBPs in neighboring blocks as coding map table reference information H2 to coding map table provider 32. Coding map table provider 32 determines a coding map table used in coding of the CBP, based on these CBPs in the neighboring blocks, and provides a coding map table H4 to variable-length code output part 30. Variable-length coding table provider 33 feeds a variable-length coding table H5 to variable-length code output part 30. Then the coding target CBP is subjected to variable-length coding, and the resultant is outputted as coded data D9. This allows information source coding of coding symbols to be performed efficiently according to the coding condition and the property of image.

Abstract: 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.

Abstract: An orthogonal transform such as a DCT is carried out for image data D5 of an image in blocks obtained by dividing a frame image, the image data D5 being represented by spatial coordinates (Step S102), and a plurality of orthogonal transform coefficients D6 as image data represented by spatial frequencies are generated. Then, the orthogonal transform coefficients D6 undergo arithmetic coding, and thus coded data D7 is generated (S103). Subsequently, in the arithmetic coding of the orthogonal transform coefficients, data characteristics of the orthogonal transform coefficients to be coded, which depend on the spatial frequencies, are considered, and a probability table is switched for a predetermined orthogonal transform coefficient, and thus the arithmetic coding is carried out.

Abstract: 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.

Abstract: Orthogonal transform coefficients D6, which are image data of a coded object, are generated by performing predetermined data transform operations on frame image D1 (Step S100), and coded data D7 is generated (S103) by subjecting the orthogonal transform coefficients D6 to arithmetic coding using a predetermined probability table. Then, in variable-length coding for generating the coded data D7, it is set whether or not a probability table is initialized at the slice layer, and a flag indicating the presence of the initialization is added to a header of a predetermined layer. Thus, the image coding method, image decoding method, image coding apparatus, image decoding apparatus, program, computer data signal, and image transmission system, which are capable of enhancing data compression efficiency by coded data in a manner that a probability table is suitably set over the entire coded data, are realized.
