The paper explores how light fields captured by plenoptic cameras can increase the performance of face landmark detection. The idea is to exploit light fields geometrical constraints to correct the position of points detected by classical face landmark detectors. These geometric constraints are used to enforce landmark points angular coherency across the different views of the light field, and by doing so to correct the positions of the landmarks on all views. The corrected landmark points are compared with ground-truth manual annotations of a set of 400 images corresponding to the central views of 400 light fields of faces with different pose and expression.
