图像检索研究综述及系统实现

利用文献可视化分析工具对图像检索研究现状进行了综述，同时设计了一种基于位置敏感哈希算法的图像检索系统。通过位置敏感哈希算法将图像的特征向量映射到哈希桶中，从而有效地降低了计算复杂度并提高了图像检索的效率。实验结果表明，文中设计的方法在检索效率以及查全率-查准率两个测度上均获得了较好的性能。

Survey and System Implementation of Image Retrieval

The paper summarizes the research status of image retrieval based on the visual analysis tools, and an image retrieval system is implemented based on Locality Sensitive Hashing. Image feature vectors are mapped to hash bucket by LSH method, thereby, the method effectively reducing the computational complexity and improves the efficiency of the image retrieval. Experimental results show that, the method in the paper are both obtain better performance on retrieval efficiency and recall - precision of two measures.
