Particle Filter is a Monte Carlo method that designed to approximate nonlinear problem. It usually used to track the target of the dynamic system only based on the color feature. The single characteristic is vulnerable to the impact on background noise, light, and some other factors. These would lead to misplace or lose the target. In order to improve the efficiency and robustness of the object tracking...
In this paper, we study in depth a new modeling method for parameter curves and surface-hyperbolic polynomial uniform B-spline surfaces with shape parameter. Based on this model, we give an example of free-form curve modeling, and analyze the effect that different shape parameters have on the curve shape. In light of computer graphics theories, we develop a space free-form surface modeling system...
In this paper, we have studied in depth hyperbolic polynomial uniform B-spline model with shape parameters. Based on this model, we have given an example of freedom curve modeling, and analyzed the effect that different shape parameters have on the change of the shape of the curves. We also developed a space freedom surface modeling system (SFSMS) on the Microsoft computer. Through the system, we...
