Abstract :
An automated method is proposed for registration of satellite remote sensing multi-spectral images having different spatial resolution and relative rotation and shift. The proposed method automatically estimates the ratio of spatial resolution and the relative rotation and shift by using a spatial correlation technique. After compensating them, corresponding point pairs are automatically generated in both images. They yield the division of the images into many triangles. The images are precisely registered by using piece-wise affine transformation for the triangles. The method is successfully applied to registration between an actual SPOT/HRV image and a LANDSAT/TM image
