In this paper, we analyze the motivation of the cooperative R&D between private S&T enterprises and state military companies from the angle of informal innovation network. The military industry is a natural monopoly industry which regulated by government. As a result, the informal innovation is a valuable way for private S&T(More)
Presents a method to quantify the facial expression. This method is based on the human facial part in MPEG4 protocol and facial muscle model, through the normalization of the facial muscle parameters, achieves a quantitative description of facial expression. It gives a concise way to make facial animations and to establish a bank of facial animation(More)
The paper presents a method to reconstruct a controllable 3D head and face model for a specific person. The 3D grid-muscle head and face model of the certain person is created after selecting key feature points from a front face photo and a left side face photo of the person, deforming the grid points and muscle vectors of a basic model. Then after texture(More)
Snake models are extensively used from its debut in image processing and motion tracking, but its poor convergence on concave boundary is a handicap for object location. Although, the GVF snake model shows high performance for this problem, but it suffers from costly computation by virtual of PDE's and another so-called critical point problem for the(More)
