Physics conceptions are introduced into image matching and definitions to the Mess,Density,Gravity Center and the Physical Feature Vector(PFV)of image are given in the paper. And a new matching algorithm based on image physical feature is proposed.

• 文章将物理学相关概念引入图象匹配中,定义了二维灰度图象的质量、密度、重心以及物理特征矢量,并由此提出了一种新的基于图象物理特征的分层匹配算法。
