摘要： A method of and system for generating reliability information (1616) for a noisy signal (1612) received through a noise-introducing channel (1606). In one embodiment, symbol-transition probabilities are determined for the noise-introducing channel (1606). Occurrences of metasymbols in the noisy signal (1612) are counted, each metasymbol providing a context for a symbol of the metasymbol. For each metasymbol occuring in the noisy signal, reliability information (1616) for each possible value of the symbol of the metasymbol is determined, the reliability information (1616) representing a proability that the value in the original signal corresponding to the symbol of the metasymbol assumed each of the possible values. In another embodiment, error correction coding may be performed by adding redundant data to an original signal prior (1600) to transmission by the noise-introducing channel (1606) and performing error correction decoding after transmission.

摘要： A joint image compression system (200, 300) and method (100) compress a target image and a reference image under a selected transform to produce a compressed difference image. The joint image compression system includes a computer readable media (210) and a computer program (220) stored on the computer readable media. The computer program includes instructions that implement selecting (110) a transform from among a plurality of transforms that includes a subset determined projective (SDP) transform, where the selected transform minimizes a cumulative mapping error (CME) for corresponding feature points in each of a target image (302) and a reference image (304). The instructions further implement applying (120) the selected transform to one of the target image and the reference image; forming (130) a difference image under the selected transform and compressing (140) the difference image to produce a compressed difference image.

摘要： A compression process (400) or system (700) constructs tables (740) associated with first locations in input data (710). Each table (500) includes entries corresponding to second locations in a reference file, and each second location identifies parts of the reference file that are candidate approximate matches for parts of the input data (710) at the associated first location. For each table (500), costs associated with differential encoding of the parts of the input data at the first location can be determined using the candidate approximate matches identified by the entries in the table. A partition of the input data using the parts for which the costs were determined can be selected to minimize a sum of the costs determined for the parts in the partition, and the parts in the partition can be encoded to compress the input data.

摘要： Provided are, among other things, systems, methods and techniques for generating a representative data string. In one representative implementation: (a) starting data positions are identified within input strings of data values; (b) a subsequence of output data values is determined based on the data values at data positions determined with reference to the starting data positions within the input strings; (c) an identification is made as to which of the input strings have segments that match the subsequence of output data values, based on a matching criterion; (d) steps (a)-(c) are repeated for a number of iterations; and (e) the subsequences of output data values are combined across the iterations to provide an output data string, with the determination in step (b) for a current iteration being based on the identification in step (c) for a previous iteration.
