A fast edge detection method based on the correlation of moving images and its application

Edge detection is one of the most important aspects of image processing. In the paper, a method of edge parameters extraction based on the vertical template in the Sobel operator is studied, combining the inter-frames correlation of the target and background in image series. This method can decrease the superfluous pixels of background and increase the processing speed of edge detection. An experiment is illustrated, which shows the effectiveness of this method and the high speed of the processing. The technology can be applied to some real-time systems such as movement detection and automatic vehicle identification.
