This research aims at investigating algorithms for 3D surface reconstruction from cross sections. We look at topologically motivated algorithms for robust surface reconstruction.
Object reconstruction is a challenging problem at the forefront of computer graphics and vision. A rather less-explored problem is of reconstruction from linear cross sections. Two types of problems addressed in this research are reconstruction from an organised set of cross sections and reconstruction from arbitrarily placed cross sections. We focus on topologically motivated methods for smooth reconstruction using concepts from the theory of homotopy continuation. The first problem is looked upon in the context of acoustic signals wherein the object cross sections show a definite geometric arrangement. A reconstruction in this case can take advantage of the inherent arrangement. The problem of reconstruction from arbitrary cross sections is a generic problem and is consequently more challenging.
