This paper proposes a digital algorithm for gray-scale/color image segmentation of real-time video signals and a cell-network-based implementation architecture in state-of-the-art CMOS technology. Through extrapolation of test-chip-data design in 0.35 μm CMOS technology and simulation results we predict that about 50, 000～100,000 pixels can be integrated on a chip in a 0.09μm CMOS technology, realizing very high-speed segmentation at about 300μsec per gray-scale/color image. Consequently real-time color-video segmentation will become possible in near future.
