Abstract :
On the basis of higher-dimension space and correlativity, a new method of image edge detection is put forward. The method of image edge detection based correlativity and differential operators and its principles of realizing this method are discussed. First, the values of some equal pixel and grey degree values of nearby pixel are acted as referenced sequence and comparative sequence respectively. Moreover, the correlativity between them is calculated after they are processed, and the edges of an image are detected based on the correlativity. Simulation shows that this method has higher precision in image detection, better antimoise ability and improving image detection effect.
