简介:古典光流动技术为计算在一样的景色的二幅图象之间的虚拟运动领域被开发,假定紧张的保存和流动领域的光滑。如果这些假设被掉,就算这些流动狂暴、分叉,如此的技术能被改编计算在不来自图象的数据的时间快照之间的明显的流动,作为在代表复杂空间与时间的动力学的流动的情况中。当成像方法被用来在试验性的应用程序分析动力学时,他们仅仅正在开始在实验室外面在设置被用于动力学计算,例如在从卫星数据的种类人口动力学的分析。在这个工作我们在场基于为计算的连续性方程和全部的变化规则化,流动在人口密度之间回答的一条变化光流动途径为phyto-和浮游动物相互作用从一个二种类的食肉动物猎物模型产生了。给从光流动生产的变化时间的向量地,从动态系统的计算方法能被采用学习在种类相互作用在场的伪障碍。这个方法允许测量在整个领域混合人口的种类,以及运输。
