A method of dam detection based on multi-source satellite images fusion is brought forward.Under the pattern of feature level fusion

this approach utilizes the advantage

which adopts commutative complementarily characters of multi-source remote sensing.First

extra the features in multi-source satellite images in turn.Then these features are fused by logic template of multi-sensor fusion to get the target detection output of the system.The result of the test proves that the approach can effectively detect and locate the dam in the large complex remote sensing image and reduce the miscarriage of justice and mistake in only one satellite image.The whole algorithm can work automatically

achieving the anticipating aim.
