WebApr 24, 2024 · In the original Canny method, the computation of the high and low threshold values depends on the statistics of the whole. input image. Most of the above existing implementations (e.g., [6][8]) use the same fixed pair of high and low threshold values for all input images resulting in a decreased edge detection performance. WebJan 8, 2013 · Canny Edge Detection in OpenCV. OpenCV puts all the above in single function, cv.Canny (). We will see how to use it. First argument is our input image. Second and third arguments are our minVal and maxVal respectively. Fourth argument is aperture_size. It is the size of Sobel kernel used for find image gradients. By default it is 3.

WebJun 22, 2024 · Accepted Answer. The 'Canny' method uses two thresholds. For example, if the threshold is [0.1 0.15] then the edge pixels above the upper limit (0.15) are considered and edge pixels below the threshold (0.1) are discarded. Now, you may have a question "what about the pixels in between upper and lower threshold"?
WebJun 18, 2013 · A threshold set too high can miss important information. On the other hand, a threshold set too low will falsely identify irrelevant information (such as noise) as important.
