Automatic features detection for overlapping face images on their 3D range models
Raffaella Lanzarotti, Paola Campadelli, N. Alberto Borghese · 2002
We describe an algorithm for the automatic features de-tection in 2D color images of human faces. The algorithm proceeds with subsequent refinements. First, it identifies the sub-images containing each feature (eyes, nose and lips). Afterwards, it processes the single features separately by a blend of techniques which use both color and shape infor-mation. The method does not require any manual setting or operator intervention. 1
