A method and apparatus for processing images (110). Clusters (156) of first features (136) identified in a first image (132) are identified. Each cluster in the clusters comprises a first group of features (159) from the first features (136). A transformation (155) for registering each cluster in the clusters with a corresponding cluster (161) comprising a second group of features (163) from second features (138) identified in a second image (134) is identified using an initial correspondence between the first features in the first image and the second features in the second image. A set of clusters (162) from the clusters of the first features is identified using the transformation identified for each cluster. A final transformation (172) for registering the first image with the second image is identified using the set of clusters. |
