Abstract :
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 (3×2) mask which is the connection of a (2×1) smoothing mask and a (2×2) differentiating mask. The processing time of 32.7 ms/frame for an image with 512×512 pixels×8 bits is attainable
