Abstract :
We designed a cell-network-based video segmentation test-chip in 0.35μm CMOS technology including a power reduction technique which activates only boundary cells of currently grown regions. The effectiveness of the proposed technique is confirmed by measurement results for a 41×33-sized cell-network, with 23μsec segmentation time (avg.) and 45.8mW power-dissipation (avg.) at 10MHz clock frequency.
