DupImageSearch


一个图像检索工程,主要是做近似重复图像检索,尝试各种方法(这里方法都不是自己实现,参考已开源方法)在部分公开数据集上的性能: 数据集

  1. Fribourg Product Image Database

  2. Stanford Mobile Visual Search Dataset

method:


(1)feature representation:

  1. 局部特征 : SIFT + VLAD

  2. 局部特征 : SIFT + Fisher Vector

  3. HSV颜色直方图 : Colorhist

  4. HSV颜色矩 : ColorMoment

  5. CNN高层特征 : cnn_fc7

(2)normalization

power law normalization

(3)hashing

some hasing method from hashing-baseline-for-image-retrieval

(4)measure

cos distance or L2 distance

代码主要用了 MatConvNet and VLFeat. 然后借鉴了 CNN-for-Image-Retrieval.
