  • Video enhancement using multiple frame techniques
    Patent number: 7215831
    Abstract: A system is provided for that improves video quality and resolution. The system include a processor configured with logic to estimate an image from at least one observed image to produce an estimated image, the observed image having a lower spatial resolution than the estimated image. The processor is further configured with logic to simulate steps of an imaging process and compression process and update the estimated image with statistical and/or deterministic information if further optimization is needed, otherwise designate the estimated image as a solution.
    Type: Grant

    Date of Patent: May 8, 2007
    Assignee: Georgia Tech Research Corp.

  • Cauchy-distribution based coding system and method
    Publication number: 20050031034
    Abstract: Embodiments of a coding system and method are disclosed. One method embodiment includes determining a Cauchy-based probability density function fit to a statistical distribution of coefficients generated from a transformed image frame block that are to be quantized, and estimating rate and distortion of quantized coefficients based on the Cauchy-based probability density function.
