总变差一范数光流场计算综述

摘要

重点回顾与总结了计算光流场的总变差线性一范数方法，简称总变差一范数（ TV-L1）方法。通过一致的形式化描述，将亮度守恒模型与梯度守恒模型过渡至全局平滑模型，并着重描述了模型的数值计算过程，透析计算原理与算法底层。最后给出了光流场可视化及质量评估方法，并对总变差一范数方法中的技术难点与下一步工作进行总结。%The method for optical flow field calculation using the Total Variation Linearly 1 norm, called the TV-L1 meth-od for short , is reviewed and summarized emphatically .By means of the coherent formal description , the bright conservation model and the gradient conservation model are transferred to a global smooth model , and the models ’ numerical computing progress , analytical calculation principle and physical level of algorithm are emphatically de-scribed .At the end , the method for visualization of optical flow fields and the method for quality assessment optical flow fields are given , and the technical difficulties of the TV-L1 and its future work are concluded .
