Motion Estimation

Track object motion between video frames

Motion estimation is the process of determining the movement of blocks between adjacent video frames. This toolbox includes motion estimation algorithms, such as optical flow, block matching, and template matching. These algorithms create motion vectors, which relate to the whole image, blocks, arbitrary patches, or individual pixels. For block and template matching, the evaluation metrics for finding the best match include MSE, MAD, MaxAD, SAD, and SSD.
