This code uses the 1024-dim IDE descriptor [1] and KISSME [2] and XQDA [3] distance metrics. To run this code, one should follow the three steps below.

1. Download the pre-computed IDE feature: http://pan.baidu.com/s/1mhBrwMG or https://drive.google.com/folderview?id=0B6tjyrV1YrHed3BnZnNaSUs3eEE&usp=sharing. Unzip it in the root folder.

2. Run "test_mars.m".

If you want to try your own descriptor or to learn new features, you should do as follows.

1. Download the dataset: http://pan.baidu.com/s/1hswMDfu or https://drive.google.com/folderview?id=0B6tjyrV1YrHeMVV2UFFXQld6X1E&usp=sharing. Training should be done with images in folder "bbox_train".

2. Bounding box feature extraction should follow the order specified in "root/info/test_name.txt" and "root/info/train_name.txt." The newly extracted feature should be loaded in line 19-20 in "root/test_mars.m"
