Edge in image processing
WebApr 11, 2024 · Conceptually, your edges aren't sharp enough because contour detection isn't the right algorithm for the task. You're trying to segment the edges of circles (using imbinarize), but then you're doing contour detection on that, which is giving you the edges of the edges of circles.So instead of doing contour detection, you should try to somehow … WebI've got a task to implement Sobel filter which is, as you know, an image processing filter for edge detection. But unfortunately, I've got no experience in image processing field, to the extent that I don't even know how images are represented in computer. Totally no knowledge in this field.

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.
