The Application of Structure Tensor in Edge Detection
This paper proposes a novel approach for edge detection by first applying the structure tensor. The method firstly presents the definition of scale vector by analyzing the structure tensor, to calculate the weight between two graph-nodes. The nature of structure tensor helps the new features retain more structure information of image, and that makes the detection more accurately. In addition, the paper also presents an anisotropy filter, replacing the Gaussian function, to average the structure tensor. The new filtering function makes structure tensor retain more information of complicated structure. In experiments conducted on various images, the algorithm shows a notable visual improvement.
