讨论了利用二维图像序列分析由非刚性运动物体组成的三维场景。提取动态目标的参数描述，并采用综合分析方法估计整个序列的时变场景参数。从参数化场景描述中合成图像，并与输入到相机的原始图像进行比较。评估合成图像与原始图像之间的帧差，以获得估计的场景参数更新。该分析方法以数据压缩算法的形式应用于可视电话场景，传输场景参数，在接收机合成输出序列。>
The analysis of 3-D scenes consisting of nonrigid moving objects using 2-D image sequences is discussed. A parametric description of dynamic objects is extracted, and the time-variant scene parameters are estimated throughout the sequence by employing an analysis-by-synthesis approach. Images are synthesized from the parametric scene description and compared with the original images input to the camera. Frame differences between the synthesized and original images are evaluated to obtain an estimated scene parameter update. The analysis method is applied to videophone scenes in the form of a data compression algorithm, whereby the scene parameters are transmitted and the output sequence is synthesized at the receiver. >
