Latest Patents

Soo-Chul Han holds a patent for a method titled "Motion estimation and compensation for video compression." This innovative encoding method aims to reduce the sizes of motion video data by utilizing a multitude of variable-sized data blocks derived from spatial translation vectors and the motion field of an image. By employing variable-block sizes, the method allows for the inter-mixing of coarse resolution data for static areas and fine resolution data for regions of complex motion within the same descriptive data block. The process involves comparing motion event areas between successive video frames and calculating a motion displacement vector for each pixel location. A data tree is constructed from these pixel motion vectors, which is then pruned to eliminate static areas. The remaining leaves of the pruned tree are encoded differentially and applied to a lossless arithmetic encoder, resulting in a significantly reduced data block that retains the highest resolution of the image.
