To qualify the method of traditional description of image, this paper combines geometric features with prior knowledge in artificial image recognition process, and proposes the method of structure description of artificial object image and the corresponding matching algorithm. It makes the graph structure of object discretization by feature points, and obtains its geometric characteristics with curve fitting. Then it describes the relationships of curves by the types of feature points, and develops the parametric model to restore the object in the image. Experimental results show that the description method has better human vision and can help computer easily restore the shape of the object in the image.
