Optical flow algorithms are difficult to apply to robotic vision applications in practice because of their extremely high computational and frame rate requirements. In most cases, traditional general purpose processors and sequentially executed software cannot compute optical flow in real time. In this paper, a tensor-based optical flow algorithm is developed and implemented using Field Programmable Gate Array (FPGA) technology. The resulting algorithm is significantly more accurate than previously published FPGA results and was specifically developed to be implemented using a pipelined hardware structure.
