%X To facilitate designers to design 3D face shapes conveniently, this paper presents a method of 3D face modeling using freehand portrait sketch. Our method has two characteristics: Firstly, pose estimation is introduced to face sketch analysis. It infers the corresponding front-view sketch from the side-view face sketch, users then can draw the free-form portrait sketch from their selected view. Secondly, multi-layer mapping is adopted to establish one-to-one correspondence between the sketch feature points and 3D face feature points, and the displacements between the corresponding feature points are calculated to generate the specified 3D face models. It guarantees that the geometrical characteristics of the strokes can be retained in the final 3D face model. The experiment results prove that the proposed method can generate novel 3D face models quickly and support the process of sketch-based face modeling efficiently.
