In this paper, a resource efficient architecture design for the circular Hough transform based on Field Programmable Gate Array (FPGA) technology is presented. The circular Hough transform is implemented to detect iris boundary in a binary edge image. A novel modular design is proposed to reduce the required memory space by 93% compared to the direct implementation while maintaining a high detection rate over 92%. The parallel-pipelined implementation of the proposed architecture demonstrates a… CONTINUE READING
