چکیده    This paper presents a new automatic change detection method of multitemporal remote sensing images based on 2d-otsu algorithm improved by firefly algorithm. the proposed method is designed to automatically extract the changing area between two temporal remote sensing images. first,two different temporal remote sensing images were acquired through difference value method of remote sensing images; then,the 2d-otsu threshold segmentation principles are analyzed and the optimal threshold of 2d-otsu threshold segmentation method is figured out by using the firefly algorithm,where the difference images are conducted with binary classification to obtain the changing category and the nonchanging category; finally,the proposed method is used to carry out change detection experiments on the two selected areas,where a variety of methods are compared. experimental results show that the proposed method can effectively and quickly extract the changing area between the two temporal remote sensing images; thus,it is an effective method of change detection for remote sensing images. © 2015 liang huang et al.
