Abstract
A method and apparatus for high-speed processing of video images of objects in a scene. Each pixel, in lines of bicolored pixels of a raster scanned video image containing at least one object, is identified as to the object of which the pixel corresponds. Adjacent bicolored pixels of the same color across a line are grouped into corresponding numbered pixel groups. Pixel groups of the same color are downwardly grouped into numbered blobs of pixel groups. When a next line pixel group occurs which is of the same color with more than one previous line pixel group, the next line pixel group is grouped as part of first occurring previous line blob. Additional pixel group matches occurring between pixel groups of a previous and next line are upwardly grouped to provide a common ancestor blob number to each blob of the pixel group in each additional pixel group match. Blobs having common ancestor blob numbers are grouped into numbered object with each blob belonging to an object so that each pixel, through a blob number, corresponds to an object number.
