为解决非刚体运动分析中模型精度和计算复杂度之间的平衡问题,该文提出了一种基 于圆锥曲线模型的弹性连接体(人体)三维运动估计方法。建立了人体三维模型,根据双目图 像序列进行基于该模型的人肢体三维变形和运动参数估计,采用圆锥曲线三维模型及其在图像 平面上投影的联系方程估计三维运动参数。人手臂运动估计实验结果表明该运动估计算法能 够正确估计人体运动参数。-To offer a good tradeoff between computational complexity and mode

Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the ima
