Abstract: Objective As traditional 3Dface construction is too much complex and has low efficiency,therefore,an interactive approach is proposed to generate realistic 3Dfaces based on one photo.Firstly,we con-structed a standardized face model database,and interactively select the facial feature points from aninput picture,and then,the best-matched face model is selected based on the features.Secondly,atriangular deformation approach and bilinear interpolation are used to achieve texture mapping from aphoto to 3Dmodel.The Alpha Fig was introduced to realize a fusion transition from the photo textureto the neutral texture.At last,a model regulator to regulate the model hierarchically was designed togenerate realistic 3Dfaces.Experimental results show that this approach is user-friendly,and cangenerate a high-quality realistic character in real time with less characteristic points.
