WebThe fuzzy logic edge-detection algorithm for this example relies on the image gradient to locate breaks in uniform regions. Calculate the image gradient along the x -axis and y -axis. Gx and Gy are simple gradient filters. To obtain a matrix containing the x -axis gradients of I, you convolve I with Gx using the conv2 function. WebMar 23, 2015 · Abstract: Edge detection is a type of image segmentation techniques which determines the presence of an edge or line in an image and outlines them in an appropriate way. The main purpose of edge detection is to simplify the image data in order to minimize the amount of data to be processed. Generally, an edge is defined as the boundary …
