摘要：Change detection is one of the most important topics in the application field of aerial images and satellite images. In this paper, a novel framework for accuracy improvement on change detection is proposed. The proposed framework consists of three parts. Firstly, the location difference between the two orthoimages for change detection is rectified globally. Secondly, the illumination change of the orthoimages from two different times is adjusted to produce the orthoimages with more unified illumination condition. Thirdly, the location difference between the two orthoimages is adjusted in more precise level of local regions. Experimental results show that the detection accuracy of change detection is greatly improved through the pre-processing of the proposed framework
