YANG Kang, WEI Min, SUN Lei. Design of adaptive threshold edge detection system based on FPGA[J]. 2019, (12): 96-99. DOI: 10.13873/j.1000-9787(2019)12-0096-04.
Aiming at the problem that the threshold of traditional Canny edge detection algorithm needs to be set artificially and has poor real-time performance
an improved median filtering algorithm combined with weighted average method is proposed to select the threshold. A real-time image edge detection system based on field programmable gate array(FPGA) is designed
which includes three modules
which are video image acquisition
image processing and image display. The experimental results verify the effectiveness of the adaptive threshold edge detection algorithm
and meet the real-time requirements at the same time.
