【Abstract】 This paper presents a new method based on both linear features and gray information of image. Use the Canny algorithm to extract the edge of two different images, then, according to the edge and gray information, find the discriminate of the images. This method is suitable for urban change-detection using high-resolution satellite image. The result of the experiment shows that the method is feasible.更多还原
