In view of the fact that the traditional change detection algorithm mainly depends on the spectral information and fails to effectively use image feature detection advantage, the authors put forward a multi-feature fusion of remote sensing image change detection algorithm. First, color histogram and edge histogram of gradient image object with multi-scale segmentation is statistically analyzed based on the calculation of each object. Then, the object color distance and edge linear characteristics distance between different periods are calculated by using the earth mover’s distance method; the adaptive weighted method is used to combine color distance and edge linear characteristics distance so as to construct object heterogeneity. Finally, the images change detection results are analyzed by using histogram curvature. The experimental results show that the method can fully fuse the color and edge line features and improve the accuracy of detection.
