A system for real time extraction of image outlines

A system for extracting image outlines at the television rate was developed. The system incorporates fourteen DSPs operating in parallel. The extraction is performed by applying a (3/spl times/2) mask which is the connection of a (2/spl times/1) smoothing mask and a (2/spl times/2) differentiating mask. The processing time of 32.7 ms/frame for an image with 512/spl times/512 pixels/spl times/8 bits is attainable.<
