  • Patent number: 7813563
    Abstract: Systems, methods, and computer program products are provided for digital signal processing, which may include obtaining a first set of digitized coefficients from source data and determining a best-fit distribution of a generalized Gaussian distribution for the set of digitized coefficients. The digital signal processing may further include applying a quantization algorithm to the first set of plurality of digitized coefficients to obtain a second set of quantizers, wherein the quantization algorithm is based at least in part on the determined best-fit distribution, and providing second set of quantizers as a compressed representation of the source data.
    Type: Grant

  • Patent number: 7805012
    Abstract: Methods and systems are disclosed for signal processing. A method includes receiving a plurality of digitized coefficients determining a best-fit distribution of a general family of distributions for the plurality of digitized coefficients, and providing a characterization of the digitized coefficients based upon the determined best-fit distribution. The system includes a memory for storing computer program instructions and a processor in communication with the memory. The processor is operable to execute the computer program instructions to receive a plurality of digitized coefficients, determine a best-fit distribution of a general family of distributions for the plurality of digitized coefficients, and provide a characterization of the digitized coefficients based upon the determined best-fit distribution.

  • Publication number: 20070165956
    Abstract: Systems, methods, and computer program products are provided for performing digital signal processing. According to one embodiment, the digital signal processing may include obtaining a first set of digitized coefficients from source data and determining a best-fit distribution of a generalized Gaussian distribution for the set of digitized coefficients. The digital signal processing may further include applying a quantization algorithm to the first set of plurality of digitized coefficients to obtain a second set of quantizers, wherein the quantization algorithm is based at least in part on the determined best-fit distribution, and providing second set of quantizers as a compressed representation of the source data.
