The Application Of Face Recognition Technology In Facial Reconstruction From Skull

Computer-assisted facial reconstruction Technology based on skull is a method that using three-dimensional digital data, Appling Anthropology theory about soft tissue thickness, make use of computer technology to reconstruct the third dimension face model and the generated model look as much as possible with the original facial characteristics of the skull.Based on the realistic modeling of computer-assisted facial reconstruction .Firstly pointed the importance of realistic in the current reconstruction process and the situation of the importance of the process has being neglected .Then illuminated by Abate(Italy),proposed a fast method to obtain the most suitable texture based on the theory of face detection and face recognition ,and then implemented the texture mapping .The main contents include:1) The automatic detection of face region and reaffirm .Research the available method of face detection, put forward a skin color model which is used to detect the face region cursorily and a BP neural network method which can judge the region whether the face exist. Bayesian decision theory was also be used to improve the veracity.2) Facial features automatic label. In view of the divided facial region, label the location of pupil, nose, mouth and the profile information by the use of color and gray-scale regional integration projection method.3) Choose the best eigenvector. The vector features that were formed by the position of human organs may include a number of attributions. This requires selecting the most representative one in those attributions, then,form the best eigenvector by using of the high distinction attribute to recognition or texture matching process .The paper researched the facial eigenvector and get the sequences ordered by their intension.4) The production of texture and texture mapping technique .construct the texture by the Won-Sook Lee's mapping method, and defined the texture coordinates through the projection method , achieve texture mapping.5) Achieved an unknown face texture matching platform and the realistic modeling platform .Based on the above theory and research, implemented a texture acquisition system and a face model texture mapping system with the current technology, Visual C++6.0,Visual C++.NET and OpenGL.
