image retrieval
Image Retrieval 使用Sift算法提取图像特征,并用bag of words模型对特征向量进行降维,将catech 256数据集 生成的特征向量输出到文件中bows.tmp中,最后用topN算法找出匹配最佳的20幅图片。 使用配置: 下载opencv2.4.8,将opencv\build\java\x64\下的dll文件放到C:\Program Files\Java\jdk1.7.0_07\bin(jdk所在目录)下, 将graduation文件夹放在F盘下(F:\\graduation\\..),将catech 256数据集解压到picture文件夹下(ImageRetri\pictures\256_ObjectCategories), 并将ImageRetri文件夹放到web服务器下即可。
