Spatial structure of objects is an important feature of images and making use of this feature properly is very important for the user in the retrieval system. However, only a third of the existing image retrieval systems use spatial features and those features are low precision features which are variant to rotation and shift. In this paper, a polygon-based spatial feature model is proposed to describe the spatial structure of objects in image. This model is a precise description and is rotation-invariant, scale-invariant and shift-invariant. The experiments show the proposed method has good performance.
