Abstract: First, it uses morphological operators to extract the skeletons for adjacent tomographic image pair. Then, skeleton matching algorithm is employed to obtain the information of translation, rotation, and scaling between skeleton pair, which is applied to get the skeleton of any interpolated image between the tomographic image pair by linear interpolation. Finally, the interpolated images are reconstructed from their skeletons with morphological operators. Since the new algorithm only processes the skeletons, it has less computational complexity and preserves the shape information of the original object to some extent. Experimental results illustrate the effectiveness of the proposed approach.
