CBIR用户查询模式及系统构建

Use Query Schema and System Construction for CBIR

分析CBIR系统的用户查询模式以及基于形状特征的检索系统构建相关技术,在系统构建中应用示例图像与采样图像两种方式对图像的形状特征进行检索,通过图像分割获取目标轮廓,利用轮廓点与兴趣点之间的空间分布关系构造形状描述函数,应用傅立叶变换提取图像特征,最后在系统检索实验中证明其有效性。

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.
