Interesting 3D Reconstruction ideas
Variational methods for dense 3D reconstruction
Do not tell the algorithm how to do reconstruction, but rather what result it should deliver.
Class of optimization methods using mathematical models instead of a series of processing steps to produce a result.
Mathematical analysis of cost function. Example: Perturbation of a sphere to get a complex object (Blender demo)
