Popis: A fast algorithm for the automatic registration of remotely sensed images obtained from satellites has been developed. The automatic section is based on an orbital model and a library of ground control points (GCPs). The real problem of an excessive searching requirement for similarity measure is tackled by using heuristic planning. This method reduces the search space to a less detailed compact size, which is later used as a plan for finding the exact co-ordinates and which confines the search window to a small region. The improved procedure has achieved sub-pixel accuracy with a substantially reduced registration time.
