| Abstract: | Based on the development needs of the key project Geographical National Conditions Monitoring project in China, we ana-lyzed lots of change detection algorithm prototypes in domestic and foreign, and selected change vector analysis method and cross-correlation analysis method for program development and improvement, and then we got the improved cross-correlation analysis meth-od.Test and accuracy evaluation results of the three methods shows that, improved cross-correlation method is better than the other two methods from time, effect and accuracy, and change vector analysis method followed.At last, we analyzed the constraint condi-tions from image preprocessing for these 3 methods. |
