Abstract
A method of determining motion in a set of input images comprises registering the images in the set to identify stationary background content therein and generating difference images based on the registered images. The input images are segmented into regions and local motion within each of the regions is estimated. A determination as to whether the regions include moving content or static content is determined based on the difference images and the estimated local motion within the regions.
