摘　　要：针对既有的红细胞仿真方法结果只展示了单个红细胞的变化过程而忽略了红细胞大规模的流动形态的问题,提出一种基于动态纹理技术进行红细胞流动过程仿真——根据所提供的动态样本,采用一种基于马尔可夫随机场模型的算法:对首帧进行初始化后利用匈牙利算法找出与结果抽样在邻域上匹配的抽样,并在结果中求解出最佳结果,得到红细胞的流动形态仿真。实验结果表明,该算法能够很好的实现红细胞的大规模流动形态仿真,具有直观的特点,满足了真实感的同时兼顾了实时性。Due to the problem that the existing simulation results shows the deformation of a single red blood cell ignoring the massive flow of erythroeyte. We propose a flow simulation of erythrocyte based on dynamic texture. According to the given dynamic samples, an algorithm based on Markov Random Field model is pro- posed. First use the Hungary algorithm to find out the matching samples of the results in the neighborhood ＇after the initialization of the first frame. Then get the optimal solution in the matching samples and simulate the flow of erythrocyte. The experimental results show that the algorithm can simulate massive flow of erythrocyte directly and visually. The result proves that it can satisfy the requirement of realistic and real - time characteristics.
