In various embodiments, methods are invoked for determining a substantially optimal entry from a bases dictionary comprising a plurality of entries; and utilizing the substantially optimal entry in a relatively low complexity matching pursuits data coding. In various embodiments, a system is provided comprising a bases dictionary comprising a plurality of entries each with a width of 15 or less; a signal to be coded; and a selection module configured to receive at least one of the plurality of entries from the bases dictionary, to calculate an inner product between the at least one of the plurality of entries and the signal to be coded, and to select the entry from the at least one of the plurality of entries that produces a maximum inner product for use in at least partially coding the signal to be coded.

Abstract: A system and method of compression is disclosed that includes the generation of position codes based on positions of individual codes. Individual codes having the same value are adjacent in the position code and are separated by a spacer code. The position codes can be generated from individual codes in increasing value or decreasing value of the individual codes. The position code can be prefixed by a maximum value of the individual codes or prefixed by a total number of the individual codes. The individual codes can be representative of an audio or a video data stream.

Abstract: A method for decoding includes receiving a message at a decoding device, where the message includes a code corresponding to a sequence of data symbols. Based on the code, a first data symbol of the sequence of data symbols is determined. The first data symbol is determined based at least in part on a first radix used to generate the code. Based on the code, a second data symbol of the sequence of data symbols is also determined. The second data symbol is determined based at least in part on a second radix and at least in part on the first data symbol.

Abstract: A method and apparatus for data compression comprises applying a decorrelating transform to multi-dimensional data to be compressed, then using a sequence of one or more one-dimensional matching pursuits algorithms to code the output of the transform. The invention finds particular application in video and still image coders, particularly real-time coders, those intended for use at very low bit rates, and those for which scalable bit rates are of importance.

Abstract: Embodiments related to coding and/or decoding data, including for example image data, using wavelet transform and matching pursuits are disclosed. In some embodiments, a wavelet transform is applied to data to produce transformed data. The transformed data is scanned to produce reduced dimension data, and a matching pursuit is performed in the reduced dimension data.

Abstract: Briefly, in accordance with one embodiment, a method of data compression is disclosed.

Abstract: A method includes receiving, at a decoding device, first contents of a buffer, where the first contents of the buffer include at least a first data symbol. The first data symbol is coded into the first contents of the buffer based at least in part on a first radix of the first data symbol. The first data symbol is decoded from the first contents of the buffer. Based at least in part on the first radix of the first data symbol, it is determined whether the first contents of the buffer include a second data symbol. The second data symbol is decoded from the first contents of the buffer if the first contents include the second data symbol.

Abstract: Embodiments related to coding data using a motion compensated transform, and replicated matching pursuits are disclosed. In some embodiments, a motion compensated transform is applied to an original image sequence to produce a transformed image sequence, and a replicated matching pursuits process is performed on the motion compensated transformed image sequence to code it.

Abstract: A method of enhancing data. A trace may be determined from a target data point in a target frame and a respective data point in an adjacent frame. At least an approximate value of the target data point may be determined from the trace.

Abstract: Techniques for data compression are provided. A data compression technique may include selecting a symbol string, being one or more characters, that occurs within a data set, generating a symbol string code corresponding to respective positions of the symbol string within the data set, successively repeating the above procedure for any additional symbol strings that occur within the data set to produce any additional respective symbol string codes, and generating a compressed data code through combining the respective symbol string codes.
