摘要：Edge detection is the basic computation in image segmentation, feature extraction and image matching. Most of the existing detection algorithms extract edges through a convolution operation in the spatial domain, which may loose the overall characteristics of the image and make the resulted edges uncompleted and unbalanced. In this paper we proposed a novel edge detection algorithm using the FFT procedure. A simple edge model and a systemic extraction steps are described. In the experiments, we compared the edges extracted by our method with those by three classical algorithms of Sobel, Prewitt and Roberts, where we use Canny's results as benchmarks. The experiments illustrate that edges produced by our algorithm are accurate, complete and balanced. © Springer-Verlag Berlin Heidelberg 2014.
