New Adaptive Differential Operator for Edge Detection

L Meng,Su Hongqi,Liu Qichun,Zhu Ran(School of Mechanical Electronic and Information Engineering,China University of Mining and Technology(Beijing),Beijing,100083,China)  
A new differential operator is proposed for edge detection based on Taylor expansion to calculate intensity difference of the image along horizontal and vertical orientations.Compared with classical first-order or second-order differential operators,its gradient magnitude calculation is more accurate,thus improving the situation in which few weak edges are detected and their approximation to the image is poor.Then,a threshold is calculated based on Otsu method from the gradient magnitude histogram,thus a new adaptive differential operator is obtained.Simulation results show that the new operator can automatically detect edges.Moreover,compared with the classical ones,it finds more weak edges especially for those images with low contrast,and has good approximation for curves and can be applied to those images with rich details such as face image.In addition,the advantages of new operator are also confirmed when it is applied to Canny detector,thus the edge detection accuracy and the efficiency are improved.
