Edge detection methods in digital image processing
You-yi Zheng, Ji Lai Rao, Lei Wu · 2010
Edge detection is one of the fundamental issues of digital image, in this paper, mathematical morphology method and several classical edge detection operators are reviewed. This paper provides two methods: Canny operator and mathematical morphology, which summaries relatively good image edge detection methods, and provides a reference for some detection occasions where requires smaller edge width in practical application.
