Motion Estimation Using User Input Displacement

The patent applies preliminary action by using user input to predict the likely position of blocks in the reference frame before the actual block matching search begins. The system calculates predicted block positions based on user input data, allowing the search to start from more informed positions rather than defaulting to the same position as current blocks. This preliminary prediction step reduces the average search distance and accelerates the motion estimation process.

The patent applies local quality by adapting the block matching search strategy based on local information from user input. Instead of uniformly searching the entire reference frame with the same effort, the system uses user input to identify regions of interest and adjusts search parameters locally. This allows concentrated computational effort in areas where accurate matching is most critical while reducing search intensity in less important regions, thereby maintaining overall matching accuracy while improving computational efficiency.
