The detected edges are displayed by combining the
horizontal and vertical edges "(1). "
This paper proposes a hardware architecture of Prewitt
edge detection. The input image is limited to 8-bit grayscale and a frame size of 256 x 256 pixels. Moving window is limited to 3 x 3 masks. The architecture is targeted for AItera FPGA using Quartus II and is capable of operating with a clock frequency of 145 MHz at 550 frames per second (fps). Verification is through synthesis only with parameters obtained from simulation on Matlab. By using the combination of both MatIab and Verilog, it can be easily import and export data to the designed hardware implementation to read and display images.
