Abstract


3D face reconstruction is one of the computer animation , computer games , computer vision and image recognition field research hotspot in computer graphics and computer vision field in recent years is the most fundamental and difficult problem . Face , most of the traditional 3D face modeling method need to extract multiple images done by modifying the general model , while three-dimensional reconstruction of a single image emerged in recent years new research directions . On through leaflets Face photos to create a realistic 3D face model on the basis of the deformable model method . First of all , through modeling software and CVL Face Database human face image export 3D face model data files , and data into a data format suitable for face modeling research . Secondly, the introduction of 3D face reconstruction method based on a single image , based on pre-estimation of the face pose parameters using principal component analysis algorithms and sparse deformation model for face shape model reconstruction , and on this basis propose the radial basis function interpolation adjustment of the reconstruction model , so that the accuracy of the three-dimensional shape of the model can be further raised . Finally, the use of the triangular mesh segmentation technology face densely aligned and meet the new quasi-Newton equation improved the BFGS algorithm texture parameter optimization , remodeling, and ultimately achieve a realistic 3D texture images of the human face reconstruction of the face model . Matlab program in the appropriate sections of the various parts of the simulation test , to solve some of the key issues in the reconstruction of three-dimensional face , and ultimately based on a single image of realistic 3D face reconstruction . Finally, analysis of existing problems, and research directions for further work and experience .
