This paper presents a scheme of approximating cylindrical models using convolution surfaces and subdivision surfaces. Firstly, an inverse Catmul-Clark subdivision is utilized to approximate the cylindrical models. Then the subdivided mesh is evolved onto the target convolution surface-based shape to produce a natural blending at branches. The initial inverse subdivision reduce the evolution iterations...
Research over the last decade has developed a wide application of 3D models. Much of this work, however, is not related to quality evaluation of 3D color models. This paper presents a novel subjective quality evaluation model that can be used to compute the difference between an original 3D color model and the other processed one. Our model jointly takes into account human visual perception of color...
