摘要:Change detection methods of remote sensing have been developed from pixel-based to feature-based and the data sources of change detection have been developed from medium-resolution to high resolution both of geometry and spectrum. But there is not a uniform evaluation standard and it's difficult to choose a proper change detection method for practical application. Thus, in this paper, a decisive change detection evaluation method and relative indexes with four aspects of geometric accuracy, attribute accuracy, operational time and algorithmic stability is proposed. All the evaluation aspects are normalized and integrated into a decision support system, which is applied to choose a proper algorithm for application. The decision support system can be complex or simple, and the weighted voting method is used in this paper. The weight values depend on the application.Based on above evaluation research, 21 experiments are carried out. According to the experiments, the evaluation method proposed is available to analyze and choose proper change detection for application. It can be applied to evaluating the advantages and disadvantages of different kinds of change detection methods. It should be investigated further for comparison of different change detection methods between images and vectors to validate it
