基于五点约束的全局光流算法

光流场是计算机视觉的一个研究方向 ,微分法是计算光流场的一个常用方法 ,分为全局方法和局部方法 ,全局方法能够得到100%的致密的光流场 ,局部方法大多只能得到稀疏的光流场 ,但局部方法在噪声情况下具有更好的鲁棒性。提出一种局部和全局相结合的方法 ,首先给出五点光流约束的局部方法 ,再结合全局方法 ,计算得到既致密又有较好鲁棒性的光流场

A global optical flow method based on five constraint points

Optical flowis a research direction of computer vision.The differential methods are widely used for computing op-tical flow.They can generally be divided into global methods and local methods.The global methods can yield100%dense optical flowfields,while most local methods can only yield sparse optical flowfields,however they are more robust under noise.we presenta local and globe compound optical flowcomputingmethod,firstthe five-point-flow-constraint method is selected as the local method,and then combined with a global method.As a result,both dense and robust optical flow fields can be obtained.
