%X This paper present a new corner detection method.Image features are represented using the theory of electromagnetics.Corners are detected in the vector potential of the field.Canny edge map is used as elemetary current density to create electromagenetic field.The vector potential of the field is calculated.We observed that corners are the saddle points in the vector potential.The saddle point detection algorithm is based on a simple template matching.The corner detection result is given.
