Outline of Final Research Achievements

In this research, we investigated high-accuracy estimation methods of motion vectors for high frame rate images and the imaging system to obtain high quality images by integrating multiple frames using the estimated motion vectors. First we proposed the high-speed and high-accuracy methods of motion estimation based on the gradient method by using a constraint equation with low estimation errors by shifting the target-pixel positions or adjusting the calculated directions as well as positions of the spatial gradients. In addition, we proposed the method to apply the estimated motion vectors to the super resolution for hardware implementation.
