摘要 提出了一种基于感兴趣区域的图像检索算法,该算法以图像中用户感兴趣的目标为研究对象,使用一种改进了的区域分割算法对图像进行目标区域分割,采用伪Zernike矩提取分割出来的区域形状特征结合其它区域特征构成检索特征向量。本文还讨论了在检索系统中用户感兴趣的区域与分割后图像目标区域的映射关系。在实验系统中证明有较高的区域准确率。 A region of interest(ROI) based image retrieval method is proposed in the paper. In themethod, objects in image of users' interesting are investigated. An improved region segmentationis presents in the method for image segment. Pseudo -Zernike moments are adapted to describefeature of region shape, combined with other features there are feature vectors for retrieve. Mapping relation of ROI and regions in image is discussed in the paper.
