Abstract
The present disclosure relates to a method of motion segmentation () in a video stream. The method comprises the steps of: acquiring () a sequence of image frames; dividing () a first frame () into a plurality of image blocks (); comparing () each image block () against a corresponding reference image block () and providing a measure of dissimilarity; for image blocks having a measure of dissimilarity less than a threshold: discarding () the image blocks, and for image blocks having a measure of dissimilarity greater than the threshold: keeping () the image blocks and further dividing the image blocks into a new plurality of image blocks (); repeating the steps of dividing () and comparing () until a stop condition is met (); generating () a motion mask () indicating areas of movement ().
