Abstract
Black borders are detected in an image frame using a grey scale image of the image frame, and an edge image of the image frame. Candidate black borders are identified using maximum grey scale values associated with rows and columns of pixels of the grey scale image of the image frame, and then validated using a sum of grey scale values associated with rows and columns of pixels in the edge image of the image frame. If the validation fails, it is presumed that no black border exists.
