Comparison of edge detectors on FPGA SoC system

Abstract

This paper explain that comparison of edge detectors used widely in video processing. The mentioned edge detectors are Sobel, Prewitt and Roberts. SoC (System on Chip) is selected for performance analysis of above edge detectors. SoC systems are suitable for video processing and its application which has both CPU and FPGA cores. In this study, firstly, real time video is received by the usb webcam into CPU part of the SoC system. This is simple than other FPGA system which has only FPGA core. Because, CPU part of the SoC system doesn’t require any special hardware to get video frame into system. CPU is running linaro operating system which is developed using linux for SoC systems. Secondly, received video frame is processed by FPGA core part of the system which has built in design for related edge detector. Finally, processed video frame is displayed on monitor. Edge detectors are compared about fps and quality of the edges.
