Abstract :
This paper presents a method for localization of landmarks on 3D faces. Gabor wavelets are used to extract the curvature of the 3D faces which is then used for performing a coarse detection of landmarks. As a second step, an ICP with a mean face is locally applied on each characteristic point in order to enhance the precision of the detection and to detect possible errors. Experiments realized on the 3D face FRGC V1.0 database show that our method provides a high precision compared to state of the art methods.
