摘　　要：手指再生技术过程需要根据手指三维图像残缺特征,对手指残缺区域进行方向和角度再生虚拟估计,一旦手指三维图像残缺信息量过少,传统的虚拟三维图像仿真方法无法取得足够信息,只能根据简单的向上、角度旋转等信息完成再生手指三维图像的仿真,效果不好。提出一种新的多媒体虚拟手指再生技术三维图像仿真方法。在手指状态空间中寻找一组样本,运用近似估计概率密度函数,降低手指再生方向估计的误差,以样本均值替代积分运算,获得状态最小方差分布,对手指残缺三维图像的方向和角度进行估计,再通过角度信息对手指残缺三维图像进行多目标融合。实验结果表明,利用该算法进行手指再生技术的虚拟三维图像仿真,能够真实的反映手指再生技术中,不同三维图像残缺特征间的关联性,从而为手指再生技术提供准确的决策依据。This paper presents a new multimedia simulation method for virtual three - dimensional image of finger regeneration technology. Firstly, a set of samples are selected in the finger state space. By using approximate proba- bility density function, the estimation error of finger regeneration direction is reduced, and the integral operation is substituted by sample mean to obtain state minimum variance distribution. Then the direction and angle of three - di- mensional image of defected finger are estimated. Through the angle information, the muhi - target fusion of the three - dimensional image of defected finger is made. The experimental results show that this algorithm can reflect the as- sociation between defects characteristics of the different three - dimensional images, and provide an accurate basis for the decision making of finger regeneration technology.
