摘要
在图像数据库中,如何有效检索和查询图像是一个重要的研究内容.文中提出一种结合组合欧拉向量与边缘方向直方图(EOH)的图像检索方法.首先,从边缘图像中提取组合欧拉向量特征进行图像检索(EEXO算法),其次,为更好地区分不同形状但欧拉特征相近的图像,将EEXO算法与EOH算法相结合提出EEXOEOH图像检索算法.实验结果表明,EEXOEOH算法与其它4种算法相比,具有较好的检索效率.
How to retrieve and query images effectively is an important research topic in the image database. An image retrieval method is proposed which integrates combined Euler vector and edges orientation histogram(EOH). Firstly, the combined Euler vector feature is extracted from the edge images for image retrieval (EEXO algorithm). Then, to make a distinction among the images which have different shapes and similar Euler features, an image retrieval algorithm named EEXOEOH is presented which combines the EEXO algorithm and the EOH algorithm. The experimental results demonstrate that EEXOEOH has higher retrieval efficiency than the other four algorithms.
