Latest Patents

Yen-Chieh Ouyang holds a patent for a "Motion estimation method and apparatus for video data compression." This invention provides an efficient method and apparatus for motion estimation in video compression. It utilizes a storage device that saves motion vectors (MVs) of a partial or entire frame, applying prediction modes as references for motion estimation of neighboring frames. The majority MV of the current frame and at least one neighboring frame serves as the initial point for searching the current frame or neighboring frames. If the movement of blocks in the previous frame differs from the frame's motion vector (FMV), the blocks or neighboring blocks undergo motion estimation. The invention also specifies predetermined threshold values to determine the need for refined pixel resolution, sub-sampling ratios, and early decisions regarding the current macroblock.
