Study on Edge Detection

Edge detection is a very important part in digital image processing. Using edge detection we can segment an element from an image or differentiate between elements. Edge detection plays a vital role in reconstruction in 2D or 3D images. It also helps to compress an image. We can find edges in an image using different types of linear and non-linear based edge detection method. In this paper, a brief study had done on Robert, Sobel, Prewitt, Canny, Log, Fuzzy logic based, Artificial Neural Network and Wavelet based edge detection methods. Compare different edge detection methods using MATLAB tools and analysis their performance. Briefly study on related work done on different field using edge detection method.
