@debin168 我用的是8G的MacBook Pro,运行时确实需要占用较大的内存,但是mac系统有缓存优化,不至于死机。可以考虑分多个文件存储特征,这样占用的内存会小一点。

我检索一张图片耗时2s多,请问这个你这个项目会继续更新,我已经在自己的环境运行起来,只是检索调优这块还不熟悉,或者说检索的精度还能再提高吗

@guandeng 我说一下两个方面调优的想法。

检索速度的优化

  1. 连续特征二值化,然后计算汉明距离。参考论文“Visual Search at Pinterest” 2.1。
  2. 按分类存储特征,检索时先对图片进行分类,然后在该分类的图片库里检索。比如电商场景下,每个商品都会有一个分类,实际有一个分类树,搜索时先判断分类,然后再在此类对应的图片库里检索。
  3. 实际生产可以借助分布式存储计算提高检索速度。

搜索经度的优化

  1. 选择更高的网络。本文使用的AlexNet是2012发表的,现在准确率已经被多种网络超过了。
  2. 结合传统的图像特征,比如SIFT。深度学习火之前有好多基于SIFT的图像检索应用。
  3. 可以尝试不同的相似度计算方法。

如果你在优化方面做了尝试,欢迎提PR。
