NOTE:

tools:
1.The python code is based on the python data science platform Anaconda2.
2.The python code is tested on Windows by PyCharm.

data:
3.The features of convolutional layer(Pool5 layer) of VGG16 for Oxford5k and Paris6k datasets are in path "data\feature".
4.The order of part detectors are in path "data\filter_select".
5.The groundtruth for Oxford5k and Paris6k datasets are in path "data\gt_files".

code:
6.Run evaluate.py, the mAP is printed.
7.Run select_filter.py to get the order of part detectors according to variances.
