A method for registering an image using a similarity criterion based on mutual information. The image to be registered is compared with a plurality of reference representations of an object, each reference representation being of a plurality of homogeneous zones. The mutual information between the image to be registered and each reference representation is calculated, on the set of homogeneous zones. The registration is given by the reference representation corresponding to the highest mutual information. The method can be advantageously applied to an aircraft aided navigation by registering images obtained by a synthetic aperture radar. |
