Edge detection, a key task in image processing, finds object and shape outlines in images. The Canny detector is a popular algorithm for this, noted for its accurate edge spotting. It works through steps like image noise reduction, gradient computation, and edge linking.

Machine learning in edge detection usually starts with the Canny algorithm, aiming to enhance it. These efforts use machine learning to improve edge identification, separating edges from other image components.

To begin, noise reduction is pivotal for spotting true edges amidst distractions. The algorithm then calculates gradients to find areas of intense change, which usually signal edges.

After finding gradients, non-maximum suppression occurs to refine these edge points. Only maximum gradients are kept. This is followed by double thresholding, categorizing edge pixels as strong, weak, or not edges.

The last Canny step is edge linking, which joins weak and strong edge pixels, creating complete edge sequences. This action constructs a clear edge map from the original image.
