WebEdge detection is an image-processing technique that is used to identify the boundaries (edges) of objects or regions within an image. Edges are among the most important features associated with images. We know … WebMost of the shape information of an image is enclosed in edges. So first we detect these edges in an image and by using these filters and then by enhancing those areas of image which contains edges, sharpness of the image will increase and image will become clearer. Here are some of the masks for edge detection that we will discuss in the ...
