Change detections are
-based on spectral classification of the input data such as post-classification comparison and direct two-date classification and
-based on radiometric change between different acquisition dates,
----image algebra methods such as band differencing, ratioing and vegetation indices;
----regression analysis
----principal component analysis and
----change-vector analysis
Lu et al, (2004) generalized the change detection methods into seven types, namely, arithmetic operation, transformation, classification comparison, advanced models, GIS integration, visual analysis and some other methods.
