MATLAB training program (SUSAN detection) SUSAN operator can testing corner can also detect edges, but corners seem to cope with Harris, margins seem than Canny. Nevertheless the idea was interesting. Main idea is this: first make a large objects, such as image and the original image. Then use a circular template using templates to loop through each pixel of the original image, each pixel within the template and the template Center pixel comparison if it is less than a threshold value, then the target image to the current position and the original image pixels is increased by one, until the end. In the target image in the original image is a corner location will take the local minimum, so doing a reverse subtraction. IMG=Max (IMG)-IMG,ifimg<g, where g is himself a given threshold, I get 2*MAX (IMG)/3 threshold, higher g, get more points. After this corner became a local maximum at the point value. Finally non-maximal suppression, removed some noise on the line.
