A subpixel multisensor image registration method based on edge and contour information is proposed in this paper. The purpose of this method is to realize subpixel matching of low-resolution images by using high-resolution images. By effectively considering the edge and contour information preserved in the multisensor images

and unifying feature-based matching and least-square matching

this method is work well in general. In addition

it is computationally efficient

and robust to noise. The application of image registration between NOAA-AVHRR

Landsat TM and 1∶1 000 000 digital map data have shown that.
