基于ROI的图像检索算法研究

Research on Image Retrieval Algorithm Based on Region of Interest

针对全局特征的图像检索不能很好地满足用户的意图和基于图像分割的检索过分依赖复杂的图像分割算法二者的不足,在基于子图的检索思想的基础上,给出了一种基于用户感兴趣区域的图像检索算法。该算法无需对图像进行复杂的分割就能提取对象特征,实验证明该算法具有简单、高效、查全率较高的优点。

The image retrieval system based on the global characteristics can not meet the needs of the users and that based on the image segmentation excessively depends on the segmentation algorithm. To overcome the shortcomings of these two systems, this paper presents a new image retrieval algorithm based on the users＇ regions of interest. This algorithm can extract the feature of object without segmentation. It is proved in the experiment that this algorithm is easilymanipulated, effectively, and with high recall.
