| Abstract: | The paper presents an algorithm for freight train ima ge segmentation based on the image segmentation theory.The profile of the freight train and cargoes on the image is obtained with the arithmetic and whether car goes exceeding the gauge or not is concluded by the location of the freight tra in and cargoes on the image.Auto image segmentation is presented based on diffe rence algorithm.It is proved that the algorithm has good adaptability,acceptab le precision and satisfied processing speed in normal climate. |
