Claim:
1. A pose rectification method for rectifying a pose in data representing face images, comprising the steps of: A—acquiring at least one test frame with a depth map camera; wherein the test frame includes 2D near infrared image data, 2D visible light image data, and a depth map; B—determining a mesh of points corresponding to a face in the depth map; C—estimating the pose of the face detected in the depth map by aligning said face with a 3D model of a head of known orientation, said step of estimating the pose including a step of minimizing a distance function between points of the depth map and corresponding points of said 3D model; D—mapping at least one of said 2D image on the depth map, so as to generate textured image data; E—projecting the textured image data in 2D so as to generate data representing a pose-rectified 2D projected image.
