Canny Edge Detector

The Canny Edge Detector is an image processing technique used to identify edges or boundaries in pictures. It works by first smoothing the image to reduce noise, then finding areas where there is a rapid change in brightness, which indicates an edge. The method uses a series of steps, including gradient calculation and non-maximum suppression, to accurately define these edges. Finally, it employs thresholding to determine which edges are strong enough to be considered significant. Overall, Canny is valued for its ability to produce clean and precise edges, making it a popular choice in computer vision and image analysis.
