Most appearance based models suffer from the unpredictability of facial background, which might result in a bad boundary extraction.

#

#

By normalizing the illumination conditions on different facial images, we extract a global illumination-invariant texture map, which jointly with the extracted 3D face structure in the form of cubic morphing parameters completely encode an individual face, and allow for the generation of images at arbitrary pose and under arbitrary illumination. Face recognition is conducted based on the face shape matching error, shapee error and illumination-normalized blog research paper error.

#

Viewing angles are roughly categorized to four different poses, and the customized view-based AAMs align face images in different specific pose categories.

Face contour is dynamically generated so that the morphed face looks realistic.

#

#

In this thesis we introduce several improvements to morphable model based algorithms and make use of the 3D face structures extracted from multiple images to conduct illumination analysis and face recognition experiments. Face contour is dynamically generated so that the morphed face looks realistic.

We also attempt at obtaining individual 3D face structures by morphing a 3D generic face model to fit the individual faces. In this thesis we introduce several improvements to morphable model based algorithms and make use of the 3D face structures extracted from multiple images to conduct illumination analysis and face recognition experiments.

We present an enhanced Rhesis Appearance Model AAMwhich possesses several sub-models that are independently updated to introduce more model flexibility to achieve better feature localization. Face recognition is conducted based on the face shape matching error, texture error and illumination-normalized texture error.

#

#

To overcome the correspondence problem between facial feature points on the generic and the individual face, we use an approach based on distance maps.

To overcome this problem we propose a local projection models that accurately locates face boundary landmarks. By normalizing the illumination conditions on different facial images, we extract a global illumination-invariant texture map, which jointly with the extracted 3D face structure in the form of cubic morphing imag completely encode an individual face, and allow for the generation business school goals essays images at arbitrary pose and under arbitrary illumination.

Furthermore, it is observed that the fusion of shape and texture information result in a better performance than using either shape or texture information individually.

We present an enhanced Active Appearance Model AAM , which possesses several sub-models that are independently updated to introduce more model flexibility to achieve better feature localization.

It is also a technology that has proven its usefulness for law enforcement agencies by helping identifying or narrowing down a possible suspect from surveillance tape on the crime scene, or quickly by finding a suspect based on description from witnesses. By normalizing the illumination conditions on different facial images, we extract a global illumination-invariant texture map, which jointly with the extracted 3D face structure in the form of cubic morphing parameters completely encode an individual face, and allow for the generation of images at arbitrary pose and under arbitrary illumination.
