نویسندگان
چکیده
A novel model matching method based on improved genetic algorithm is presented in this paper to improve efficiency of matching process for 3D face synthesis. New method is independent from initial values and more robust than stochastic gradient descent method. Improved genetic algorithm has strong global searching ability. Crossover and mutation probability are regulated during optimization process to improve precision and convergence speed of the algorithm. Experimental results show our new model matching method has good performance on 3D face synthesis.

متن کامل3 D Face Animation Based on Morphable Model ?
We present a 3D face animation method based on the morphable model. Given a facial image, the 3D face can be reconstructed automatically by the morphable model. So it is feasible to animate any face with the model. To construct the morphable model, a set of neutral 3D faces are acquired and aligned. A general parameterized animation model is constructed from expressive 3D faces and used to anim...
متن کاملFace Recognition and Growth Prediction using a 3D Morphable Face Model
We present two different techniques and applications that are based on the 3D Morphable Face Model. In the first part of this thesis, we develop a new top-down approach to 3D data analysis by fitting a 3D Morphable Face Model to 3D scans of faces. The algorithm is specifically designed for scans which were recorded in a perspective projection. In an analysis-by-synthesis approach, shape, textur...
متن کاملMorphable Face Models - An Open Framework
In this paper, we present a novel open-source pipeline for face registration based on Gaussian processes as well as an application to face image analysis. Non-rigid registration of faces is significant for many applications in computer vision, such as the construction of 3D Morphable face models (3DMMs). Gaussian Process Morphable Models (GPMMs) unify a variety of non-rigid deformation models w...
