This paper describes two new methods for the reconstruction of discrete surfaces from shading images. Both approaches are based on the reconstruction of a discrete surface by mixing photometric and geometric techniques. The processing of photometric informations is based on reflectance maps which are classic tools of shape from shading. The geometric features are extracted from the discrete sur...

We present a differential geometric approach for cylindrical anatomical surface reconstruction from 3D volumetric data that may have missing slices or discontinuities. We extract planar boundaries from the 2D image slices, and parameterize them by an indexed set of curves. Under the SRVF framework, the curves are represented as invariant elements of a nonlinear shape space. Differently from sta...

The field of surface reconstruction has been steadily evolving for the past couple of years. The inclusion of Artificial Intelligence (AI) is a one more step to attain the efficiency and accuracy. Some previous studies on surface reconstruction with unstructured data always point out the issue of how to restructure the scattered data point. Another issue is on the complexity of the algorithm th...
