How does canny edge detection work

WebIntroduction. Canny edge detection is a image processing method used to detect edges in an image while suppressing noise. The main steps are as follows: Step 1 - Grayscale Conversion. Step 2 - Gaussian Blur. Step 3 - Determine the Intensity Gradients. Step 4 - Non Maximum Suppression. Step 5 - Double Thresholding. WebThe Canny method applies two thresholds to the gradient: a high threshold for low edge sensitivity and a low threshold for high edge sensitivity. edge starts with the low sensitivity result and then grows it to include …
