摘要
该系统将Bag of words模型用于大批量图像检索,基于OpenCV C语言库提取图像的SIFT特征,然后使用Kmeans算法进行聚类,再将其表示成Bag of words矢量并进行归一化,实现大批量图像检索,并用caltech256数据集进行实验。实验表明,该系统该系统采用的方法是有效的。
The system will be Bag of words model used in large quantities of image retrieval,based on OpenCV C library image SIFT fea ture extraction,and then use Kmeans clustering algorithm,and then it says a Bag of words and vector normalization,realizing mass image retrieval,and caltech256 data set for experiments.Experiments show that the system adopts the method is effective.
