    Canny Edge Detector Implementation - Tom Gibara

    The short video below was created during the testing and optimization of this implementation. I chose a 'comic styled' video clip in the expectation that its stylization would be favourable to the algorithm. With the implementation of the PHOG descriptor I came around the situation that no well-performing Canny Edge Detector in pure Java was available. “Pure” in my case means, that it just takes a Java BufferedImage instance and computes the edges. Therefore, I had to implement my own 🙂 Code. What does this program do?

    The Canny edge detector is an edge detection operator that uses a multi-stage algorithm to detect a wide range of edges in images. It was developed by John F. Canny in 1986. Canny also produced a computational theory of edge detection explaining why the technique works. There are hundreds of different edge detection methods, including Sobel, Roberts, SUSAN, Prewitt, and Deriche. All edge detection methods have pros and cons, and Canny is just one of them. In general, canny edge detection tends to yield good results in most scenarios, so it is well-suited for general use. This is a new method of edge detection and it is flexible and scalable. Background. I had the need for a flexible and scalable edge detection. So, I could use sobel, prewitt or canny. In sobel & prewitt, it is hard to change the edge thickness. But my edge detection has only a threshold value, if you change it, output will be different. Why is ...
