摘　　要：研究建筑设计方案的计算机虚拟图像序列与真实环境图像序列相合成时 ,分割边缘随时间而变化的动态掩模问题 ,提出了基于关键帧的闭合B样条曲线拟合真实环境图像序列分割边缘的动态掩模插值算法 ,和掩模分割曲线样本点运动关键帧的判定规则 。The dynamic masking in the synthesis between the virtual computer image sequence of architecture scheme and the real environmental image sequence has been investigated where the segmentation edge varies with time. A keyframe based interpolation algorithm of dynamic masking by tracking the segmentation edge of foreground with closed B spline and rules for judging the motion keyframe of sample point on the segmentation spline are put forward. The experimental result shows that the algorithm is valid and viable for the application in practice.
