An algorithm for building deformable 3D human face models and justification of its applicability for recognition systems

In the article, an algorithm for constructing deformable face models, based on the use of Active Shape Model method, Shepard method of landscape surfaces restoring and set of 3D particular face models, is described. Alternative to the EER, the assessment of accuracy in the task of the person recognition using their face image based on an anchored value of FAR is offered. The results of testing the algorithm are presented. We demonstrate the results of using the obtained models within the framework of recognition algorithm performance on a large base of several thousand images (FERET image database by 2000 year),which contains photographs of people at angles of 0, 45 and 90 degrees relative to the optical axis of the camera. Analysis of the results showed that the use of deformable face models does not reduce the quality of the person recognition by face image even under difficult initial conditions and in some cases leads to improving recognition results.
