WebApproaches of edge detection The method for edge detection is classified into two categories; first is gradient based and second is Laplacian based. In the gradient based method edges are detected by taking the first order derivative of the image. The gradient magnitude is used to calculate a measure of edge strength. Gradient magnitude has the Webthat for edge detection, there is a tradeoff between noise reduction (smoothing) and edge localisation. – A form of optimal edge detection • Reference: – Canny, J., “A computational approach to edge detection”, IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986, 8(6):pp.679-698
