| Abstract: | The scale, shape and position are three main factors to forecast tropical cyclone. The aim of the paper is to recognize tropical cyclone （TC） in the satellite cloud pictures according to the scale, shape and position of clouds. The study includes Canny edge detection, contour extraction and other techniques. The solutions are also established. The experiments show that the method can recognize the TC in the satellite pictures. The study is beneficial for TC track. |
