This paper presents an automatic elastic registration of medical images based on Renyi entropic minimum spanning graph and multi-quadric radial basis function.Images are layered and blocked based on image pyramid process and its sub-image blocks are registered using Renyi entropic minimum spanning graph’s similarity measure.Landmark points in corresponding sub-image blocks are extracted.Those landmark points are interpolated via multi-quadric radial basis function so as to achieve elastic registration of medical image.Experimental results indicate that the method is a fast,accurate and effective elastic registration of image.
