Abstract: A method of locating a single image in a field of images by scanning the field in a stream of video elements, interrogating said elements with a logic to produce a set of cells each representing a relatively small portion of a single image, and recombining said cells with another logic to produce a block representing an area containing said single image separated from its neighbours. An apparatus for locating a single image in a field of images, comprising a scanner (110) to produce a stream of video elements representing said field, an image memory (130) to store said video elements, a logic (151, 160) responsive to said elements to produce a set of cells each representing a relatively small portion of a single image, and another logic (153) responsive to said set of cells to produce a block representing an area containing said single image separated from its neighbours.
