| Summary: | 碩士 === 國立交通大學 === 資訊科學系 === 89 === Interpolation is an important processing step in 3-D reconstruction. In many medical and other scientific applications, a 3-D object must be reconstructed from serial cross sections, either to aid in the comprehension of the object’s structure or to facilitate its automatic manipulation and analysis. If the cross sections are not closely spaced, interpolation is needed to recapture the appearance of the embedded 3-D object. A new method, based on mathematical morphology, is presented here to implement the interpolation by using scaling transform and morphological median concept. Compared with previously proposed methods, the new approach successfully resolves the interpolation problem when there is narrow concavity or sharp invagination in the interpolated objects. In the mean time, it has a wide adaptability and is easy to implement.
