Abstract :
This paper presents an effective registration method between two geophysical images from different modalities, namely magnetic and electrical, in order to increase the information obtained from the two original images independently. In order to achieve the registration, random local transformations were applied in 5×5 randomly chosen windows of the sensed image while the mutual information was used as the similarity measure. The results, in all cases, show a significant increase in mutual information in comparison with the registration through geographical coordinates.
