3D Facial Landmark Tracking and Facial Expression Recognition [PDF]
Journal of information and communication convergence engineering, 2013 In this paper, we address the challenging computer vision problem of obtaining a reliable facial expression analysis from a naturally interacting person. We propose a system that combines a 3D generic face model, 3D head tracking, and 2D tracker to track facial landmarks and recognize expressions.

Compensating inaccurate annotations to train 3D facial landmark localisation models [PDF]
, 2013 In this paper we investigate the impact of inconsistency in manual annotations when they are used to train automatic models for 3D facial landmark localization. We start by showing that it is possible to objectively measure the consistency of annotations
