Recursive region splitting at hierarchical scope views

Abstract There are several limitations of the recursive region splitting algorithm for image segmentation. The recursive region splitting at hierarchical scope view is a new algorithm to ease some of the difficulties. A quad tree structure is used to store the split results of the scope views at different levels. The segmentation will proceed to small scope views only if the result at that level is not satisfactory according to a certain criterion. Experimental results of applying this new algorithm to aerial photographs shows improved sensitivity to detect smaller objects. A boundary check procedure is implemented in this algorithm to remove boundary discontinuity along the scope view border. The segmentation results and processing time of four sets of aerial photographs are also discussed here.
