A Deep Signed Directional Distance Function for Object Shape Representation

  title={A Deep Signed Directional Distance Function for Object Shape Representation},
  author={Ehsan Zobeidi and Nikolay A. Atanasov},
Neural networks that map 3D coordinates to signed distance function (SDF) or occupancy values have enabled high-fidelity implicit representations of object shape. This paper develops a new shape model that allows synthesizing novel distance views by optimizing a continuous signed directional distance function (SDDF). Similar to deep SDF models, our SDDF formulation can represent whole categories of shapes and complete or interpolate across shapes from partial input data. Unlike an SDF, which… Expand
