In Edge detection is one of the most fundamental algorithms in digital image processing. The Canny edge detector is the most implemented edge detection algorithm because of its ability to detect edges even in images that are intensely contaminated by noise. In this paper, a modified canny edge detector is designed implemented in MATLAB and implemented in FPGA. The mask for gradient calculation and in non-maximal suppression bilinear interpolation of four pixels are considered. This edge detector is implemented as a preprocessing stage in iris detection subsystem. The motivation in designing the hardware modules of canny edge detector was to reduce its complexity, enhance its performance and to make it suitable development on a reconfigurable FPGA based platform for VLSI implementation.
