Morphology-based interpolation for 3D medical image reconstruction.

Interpolation is an important processing step in 3D reconstruction. A new method, based on mathematical morphology, is presented here to implement the interpolation by means of a combined operation of weighted dilation and erosion. Compared with previously proposed methods, the new approach successfully resolves the interpolation problem when there is no overlapping area between the two objects. In the mean time, it has a wide adaptability and is easy to implement.
