Abstract :
This paper introduces a method for automatic registration and fusion of multi-resolution SAR and TM images. We use a new model to extract and match features from multi-resources images, and register the images by affine transformation using accurate RCPs derived by feature-based algorithms. After registration, we fuse SAR and TM images by ratio method. The result shows that the algorithm is efficient.
