Face recognition

We present a novel method for automatic 3D face authentication. A coupled 2D and 3D feature-extraction method is introduced, and the bilateral symmetrical plane is used for calibration and precise registration. The central profile which is on the bilateral symmetrical plane is the foundation for recognizing human face in our method. We use a weighting function for ICP according to the bilateral symmetrical behavior. We take 2.5D range image and its corresponding texture as the input data and compare the scanned model with the specified database model. The value of the weighted distance between two compared models is used for authentication. The result illustrates that this method work well in self authentication.

Simulation and Analysis of Interfacial Wettability by Dissipative Particle Dynamics

We present a three-dimensional dissipative particle dynamics simulation, which is independent of the initial conditions, for analyzing the wettability on liquid-solid interfaces. The model parameters are constructed based on simulation optimization. The contact angle of a droplet on the solid platforms which possess different surface energy is simulated. By tuning the attractive effects between the platform and the droplet, the contact angles are found at steady states. Moreover, the local density and the equation of state are applied for determining the droplet’s self energy and compressibility. The simulation results will help us to predict the profile and internal physical behavior of a micro-droplet.
