3D Face Model Estimation based on Similarity Transform using Differential Evolution Optimization

K. Punnam Chandar, T. Satya Savithri
2015 Procedia Computer Science  
3D Face model reconstruction from a single 2D image is fundamentally important for face recognition because the 3D model is invariant to changes of viewpoint, illumination, background clutter and occlusions  ...  Experimental results on 2D Head Pose and 3D Bosphorus databases demonstrate the feasibility and efficiency of the proposed methods.  ...  As from the literature two well-known projection models are available, the perspective and the orthographic.  ...

A.S. Georghiades, P.N. Belhumeur, D.J. Kriegman
2001 IEEE Transactions on Pattern Analysis and Machine Intelligence  
The pose space is then sampled and, for each pose, the corresponding illumination cone is approximated by a low-dimensional linear subspace whose basis vectors are estimated using the generative model.  ...  We test our face recognition method on 4,050 images from the Yale Face Database B; these images contain 405 viewing conditions (9 poses 45 illumination conditions) for 10 individuals.  ...  The 64 images of a face in a particular pose are acquired in about two seconds. Therefore, there is only minimal change in head position and facial expression in those 64 images.  ...

Lifelike talking faces for interactive services

E. Cosatto, J. Ostermann, H.P. Graf, J. Schoeter
2003 Proceedings of the IEEE  
The traditional model-based approach uses three-dimensional wire-frame models, which can be animated from high-level parameters such as muscle actions, lip postures, and facial expressions.  ...  Beside lip articulation, a talking head must show appropriate head movements, in order to appear natural. We illustrate how such "visual prosody" is analyzed and added to the animations.  ...  In this method, the pose is first estimated using a scaled orthographic projection, and then it is iteratively refined to match a perspective projection.  ...
