image retrieval

图像检索

这个项目会逐渐合并到cnn-cbir-benchmark

开始整理这两三年自己在image retrieval的一些资料,方便来年的毕业设计。

查询时间:查询时间是单词查询的结果,并没有进行多次查询进行平均,此外查询时间是查询和计算mAP时间的总和。

MSER

MSER得到椭圆区域后,再结合SIFT,可以剔除掉很多没用的点,VLFeat中的MESR例子见这里。此外MSER还可以用于文本区域筛选中,具体可以看这个Robust Text Detection in Natural Scenes and Web Images。概念与作用相关词:漫水填充法、显著性。

基于SIFT特征点匹配

SIFT on GPU (SiftGPU), works for nVidia, ATI and Intel cards.
