WebJan 8, 2013 · Canny Edge Detection is a popular edge detection algorithm. It was developed by John F. Canny in. It is a multi-stage algorithm and we will go through each stages. Noise Reduction. Since edge detection is susceptible to noise in the image, first step is to remove the noise in the image with a 5x5 Gaussian filter. Sudden changes in pixel intensity characterize edges. We need to look for such changes in the neighboring pixels to detect edges. Let’s explore using two important edge-detection algorithms available in OpenCV: Sobel Edge Detection and Canny Edge Detection. We will discuss the theory as well as demonstrate … See more Sobel Edge Detection is one of the most widely used algorithms for edge detection. The Sobel Operator detects edges marked by sudden changes in pixel intensity, as shown in the figure below. The rise in intensity is even … See more Canny Edge Detection is one of the most popular edge-detection methods in use today because it is so robust and flexible.
