TV minimization of direct algebraic method of optical flow detection via modulated integral imaging using correlation image sensor

A novel mathematical method and a sensing system that detects velocity vector distribution on an optical image with a pixel-wise spatial resolution and a frame-wise temporal resolution is extended by total variation minimization. We applied fast total variation minimization technique for exact algebraic method of optical flow detection. Simulation result showed that directional error caused by local aperture problem decreased effectively by the virtue of global optimization. Experimental results showed edge preserving characteristics on the boundary of motion.
