Examples

Techology part

The most of the algorithms are written using openCV

Face detection: Haar Cascade
Keypoint detection: The cascade of regressors using dlib based on this paper
Face triangulation: simple Triangulation
Reconstruction: Affine projection each triangles
Color alignment: Seamless Cloning (details)
