| Abstract: | The air-photos are separated by wavelet transform,and its low frequency part is save.Then we use SIFT algorithm to match the low frequency images.We find that the solution to the problem that some application need a fast match.The experiment result show that this kind of method have faster matching speed and higher matching accuracy. |
