Abstract

Summary This paper proposed that an advanced algorithm for selecting a seam line automatically which used to be selected by human operator for mosaicking images. The presented algorithm is based on the identification induced by the correlation and the direction of tie points. Tie points were selected from two geometrically distored spatial ortho-images. And the identification of selected tie points were represented by FOM. Additionally, four factors were taken into account for weights of the directed graph. These five factors were adjusted finely to work equally on selecting seam line. Then, the Dijkstra algorithm was executed repeatedly after each line adjustment. Using the seam line selected by this method, two spatial orthoimages were merged, and the effect of the identification of tie points was analyzed.
