Demo : Point-Feature Tracking for Pixel Processor Arrays

Abstract

We demonstrate our "in-pixel" point-feature detection and tracking approach, designed specifically for Pixel Processor Array (PPA) sensors. PPAs consist of thousands of "pixel-processors", enabling massive parallel computation at the point of light capture. Our approach performs all computation for feature detection & tracking within these pixel-processors, allowing sensor output to be reduced to just sparse event like feature locations & descriptors, entirely avoiding the need to transfer images off-sensor. We implemented our approach upon the SCAMP-7 PPA prototype, upon which it can operate at just over 3000 FPS (Frames Per Second) given sufficient illumination, allowing real-time point-feature tracking under violent motion.
