In this paper, the user query schema of CBIR is discussed, and the technology of shape-based retrieval system is analyzed. Two query ways using example and sample image are used in the experiment system construction. Image segmentation technology is used to acquire the target contour. In the shape description step, the spatial relationship between contour points and salient points are established by the relation function, and the image features are extracted by using Fourier transform. Experiments with a combined dataset witness the effectiveness of the system, which has certain reference significance to the research of relevant technologies in digital libraries.
