Canny edge detection based on Open CV
Xu Zhao, XU Bao-jie, Guoxin Wu · 2017
As a traditional edge detection algorithm, Canny operator is widely used and improved. Canny adopts hysteresis threshold, the different values of threshold have great influence on the detection result, but the number can not reflect the detection result intuitively. Four of algorithms are introduced through the use of Open CV programming, the programming can visually display the detection results under different thresholds, which is convenient for image edge detection.
