Latest Patents

Narindra N Puri holds a patent for a process titled "Motion compensation image interpolation—frame rate conversion for HDTV." This patent describes a method for up-converting an existing video source signal with a low frame rate to a high-frequency signal suitable for HDTV. The process involves sampling existing frames and calculating integer displacements of pels within those frames. A polynomial curve fit is then applied to estimate horizontal and vertical displacements of each block in the frames. By segregating blocks into groups based on their alignment within a sampling grid, the method interpolates missing frames in a piecemeal manner, utilizing blocks from specific groups to estimate corresponding blocks in the high-frequency signal.
