Abstract
A 128(H)×64(V)×RGB CMOS imager is integrated with region-of-interest selection, RGB-to-HSI transformation, HSI-based pixel segmentation, 36-bins×12bits HSI histogramming and sum-of-absolute-difference template matching. 32 learned color templates are stored and compared to each image. Running at 30 fps, it uses 1 mW.
