Body-structure-based cartoon character modeling from multi-view hand-drawings

Hand-drawn cartoon has the characteristics of flexibility, natural expression and so on. We present a multi-viewpoint hand-drawn character modeling method based on the human body structure, which is used to express the cartoon character model of hand-drawn style. Firstly, the two-dimensional skeleton is extracted, the skeleton depth is acquired and the three-dimensional skeleton is generated by the human body structure model. Then, combined with the expansion algorithm and the surface optimization and subdivision algorithm, the local networks matched with the multi-view hand-drawn contour lines are created and combined into the whole network model. Finally, the skeleton subspace deformation is established by using the thermal diffusion algorithm. Thereby a three-dimensional character model is generated. The experimental results show that this method can effectively generate cartoon character model with hand-drawn style.
