| Abstract: | An automatic method based on corner features for the registration of remote sensing image was proposed in this paper.In this registration scheme,Harris operator was developed to detect corner features adaptively.Then the registration was conducted from roughly to fine.Experiments were carried out on MODIS images,TM images and HJ-1 images whose resolution are different.The results demonstrated that the proposed method could make registration accuracy up to sub-pixel,which can be a registration method of high precision. |
