Latest Patents

Chang Sun holds a patent for a "System and method having transparent composite model for transform coefficients." This invention addresses the flat tail phenomenon commonly observed in transform coefficients, such as DCT coefficients. The system utilizes a transparent composite model (TCM) to effectively separate the tail of a sequence from its main body. By employing various distribution models, including uniform and truncated Laplacian distributions, the TCM can accurately model the transform coefficients in the flat tail while using parametric distributions for the main body. The parameters of the TCM can be estimated through maximum likelihood or greedy estimation techniques.
