On the Methods of the Object Recognition Based on the Invariant
基于目标不变量的识别方法研究

The object recognition based on the object invariant is the most active research area in computer vision. This paper summarizes the invariant theory and a variety of the invariants by now,and compares their advantages and disadvantages. Furthermore ,the paper suggests some future research directions on the invariant theory and discusses its application in the computer vision and the content based image retrieval.
