  • A Feature-Index based algorithm that uses
    similarity information and spatial coherence is presented in
    the paper. It especially ¯ts to the case that the base image
    is very large and real-time property is needed. The algo-
    rithm is divided into four steps: ¯rstly extract features
    from base image, and establish feature-index table before-
    hand; then extract corresponding features from sensed im-
    age and use the feature-index table to match them with
    those from base image; thirdly, fuse the matching results
    of Main line pairs (MLPs) and contours; ¯nally, solve the
    transformation parameters using the intersection points of
    MLPs and centers of contours and complete registration.
    The experiment results show that the proposed algorithm
    is accurate and e®ective.
