ABSTRACT:
A method of analyzing multiple frames of image data wherein each frame is represented by a matrix of pixels fed serially from a source for processing. A first frame of pixels is transformed in at least one serial neighborhood transformation stage to detect spatial locations associated with given objects in the frame. A second frame of pixels is subsequently transformed to detect the spatial locations associated with the objects in that frame. Then, the differences between the transformations of the first and second frames are analyzed to detect changes in the number of and/or location of the objects between frames.
