Real-time computing of optical flow using adaptive VLSI neuroprocessors

The multilayer stochastic neural network and its associated VLSI array neuroprocessors are presented for VLSI optical flow computing. This network is well-suited to VLSI implementation due to the high parallelism and local connectivity. Instead of using deterministic scheme, a stochastic decision rule implemented with electronic annealing techniques is used to search optimal solutions. VLSI array neuroprocessor architecture is proved to be an effective supercomputing hardware for real-time optical flow applications. A prototype 25-neuron chip for this VLSI array neuroprocessors (called a velocity-selective hyperneuron chip) has been implemented using MOSIS 2-μm CMOS technology. A real-time optical flow machine is feasible by using arrays of hyperneuron chips
