Estimating high quality surface normals of objects is often problematic in computer graphics. We often use local and global geometric methods. In local methods, we are going to estimate a normal by using the nearing normals in a 3D model, in global this is often an optimization problem which uses all the model.
A recent exploited method is to estimate the normal by looking at the same object from different lighting conditions. The amount of light reflected by a surface (under Lambertian reflectance assumptions) is dependent on the orientation of the surface in relation to the light source and the observer.

One interesting advancement would be to use all the light spectrum to let real-time acquisition of the normals of a scene composed of dynamic objects.

Student:

• Good skills at programming (C++/Python)
• Interested in physics and optics.
  No prior knowledge in computer graphics or in the normal estimation problem needed.
