A method for circular pattern recognition in a binary image and its implementation onto an FPGA are described. The proposed method is based on the template matching method using a modified matching degree. This method is implementable onto an FPGA and can realize a real-time system. The usefulness of the proposed method was confirmed by numerical simulations. The real-time performance was confirmed by experiments on the FPGA designed by using Verilog-HDL CAD tool.
