Progress in Natural Science:Materials International 2004年第6期 62-73页

Constructing a convexity-preserving interpolating curve according to the given planar data points is a problem to be solved in computer aided geometric design (CAGD). So far,almost all methods must solve a system of equations or recur to a complicated iterative process,and most of them can only generate some function-form convexity-preserving interpolating curves which are unaccommodated with the parametric curves,commonly used in CAGD systems. In order to overcome these drawbacks,this paper proposes a new method that can automatically generate some parametric convexity-preserving polynomial interpolating curves but dispensing with solving any system of equations or going at any iterative computation. The main idea is to construct a family of interpolating spline curves first with the shape parameter α as its family parameter;then,using the positive conditions of Bernstein polynomial to respectively find a range in which the shape parameter α takes its value for two cases of global convex data points and piecewise convex data points so as to make the corresponding interpolating curves convexity-preserving and C 2 (or G 1) continuous. The method is simple and convenient,and the resulting interpolating curves possess smooth distribution of curvature. Numerical examples illustrate the correctness and the validity of theoretical reasoning.

运动补偿预测、视差补偿预测以及两者相结合的联合补偿预测是研究立体视频编码的关键技术。不同预测模式不仅考虑了左右视频通道各自的时间相关性、而且考虑到了左右视频通道之间的空间相关性。本文提出了一种自适应选择预测模式的立体视频编码算法,并在预测模式确定后通过选取不同的加权值来达到联合补偿预测的目的。实验结果表明,本文提出的算法在改善编码性能的同时,提高了编码速度。
