Improved Self-Adaptive Edge Detection Method Based on Canny
Hao Geng, Luo Min, Feng Hu · 2013
The premise of obtaining the clear object contour in traditional Canny operator is to set appropriate parameters, does not have the adaptive ability. An adaptive Canny edge-detection method is proposed which Based on Canny theory. Adopt the 3*3 neighborhood instead of Canny algorithm in 2*2 neighborhood to calculate the calculation gradient. Then, the maximum between-class variance (Otsu) method is used to obtain the high and low thresholds. Experiments show that, this algorithm can get good edge detection.
