This paper investigates the use of wavelets to automatically register remotely sensed images. The proposed algorithm is based on the Laplacian of Gaussian (LoG) filter to automatically extract ground control points and the discrete wavelet transform (DWT) for multiresolution analysis. The structural properties of the wavelet coefficients can be exploited in a unique fashion to reduce the search space for the control points. The inherent multiresolution
processing of the image data provides an efficient method for registering large image data sets because the full-size does not require processing.
