OpenCV: Canny Edge Detection
WebOct 2, 2009 · A method of image processing is provided which includes non-recursive hysteresis thresholding in Canny edge detection. The non-recursive hysteresis thresholding reduces computational complexity and eliminates the potential for call stack overflow. More specifically, hysteresis thresholding is performed in a raster-scan order … WebThe thresholder used in the Canny operator uses a method called "hysteresis". Most thresholders used a single threshold limit, which means if the edge values fluctuate … inbuilt swap function in java
