Latest Patents
One of his latest patents is titled "Filter banks for enhancing signals using oversampled subband transforms." This invention focuses on the subband decomposition of a d-dimensional input signal into multiple subband components. The filter bank includes a filtering module that transforms the input signal into a low-frequency component and higher-frequency components, which are oversampled. This method allows for further decomposition and enhancement processing, making it suitable for applications such as thresholding and noise reduction.
Another notable patent is "Frame buffer compression for video processing devices." This invention involves applying a local multiscale transform to compress video signals. The coefficients of the video signal are organized into blocks, and a common exponent is determined for encoding these coefficients. This innovative approach improves the efficiency of video processing and storage.
