| Abstract: | Radiometric normalization of multi-temporal satellite images is very important for change detection or image mosaic.Existing radiometric normalization methods can be categorized as either absolute radiometric normalization or relative radiometric normalization.The methods of each category are described and reviewed,including their advantages,disadvantages and adaptability in different situations.In addition,the development trends of radiometric normalization methods for analyzing multi-temporal satellite images in the future are discussed. |
