The new protocol splits the CUHK03 dataset into training set and testing set, which consist of 767 identities and 700 identities respectively. In testing, we randomly select one image from each camera as the query for each identity and use the rest of images to construct the gallery set.
The new training/testing protocol split for CUHK03 in our paper is in the "evaluation/data/CUHK03/" folder.

Requirements for Caffe
and matcaffe
(see: Caffe installation instructions)
-
Build Caffe and matcaffe
cd $Re-ranking_ROOT/caffe # Now follow the Caffe installation instructions here: # http://caffe.berkeleyvision.org/installation.html make -j8 && make matcaffe
-
Download pre-computed imagenet models, Market-1501 dataset and CUHK03 dataset
Please download the pre-trained imagenet models and put it in the "data/imagenet_models" folder.
Please download Market-1501 dataset and unzip it in the "evaluation/data/Market-1501" folder.
Please download CUHK03 dataset and unzip it in the "evaluation/data/CUHK03" folder.
- Training
cd $Re-ranking_ROOT
# train IDE ResNet_50 for Market-1501
./experiments/Market-1501/train_IDE_ResNet_50.sh
# train IDE ResNet_50 for CUHK03
./experiments/CUHK03/train_IDE_ResNet_50_labeled.sh
./experiments/CUHK03/train_IDE_ResNet_50_detected.sh
- Feature Extraction
cd $Re-ranking_ROOT/evaluation
# extract feature for Market-1501
matlab Market_1501_extract_feature.m
# extract feature for CUHK03
matlab CUHK03_extract_feature.m
- Evaluation
# evaluation for Market-1501
matlab Market_1501_evaluation.m
# evaluation for CUHK03
matlab CUHK03_evaluation.m
You can download our pre-trained IDE models and IDE features, and put them in the "out_put" and "evaluation/feat" folder, respectively.

Using the above IDE models and IDE features, you can reproduce the results as follows:
- Market-1501
Methods | Rank@1 | mAP |
---|---|---|
IDE_ResNet_50 + Euclidean | 78.92% | 55.03% |
IDE_ResNet_50 + XQDA | 77.58% | 56.06% |
For Market-1501, these results are better than those reported in our paper, since we add a dropout = 0.5 layer after pool5.
- CUHK03 under the new training/testing protocol
Labeled | Labeled | detected | detected | |
---|---|---|---|---|
Methods | Rank@1 | mAP | Rank@1 | mAP |
IDE_CaffeNet + Euclidean | 15.6% | 14.9% | 15.1% | 14.2% |
IDE_CaffeNet + XQDA | 21.9% | 20.0% | 21.1% | 19.0% |
IDE_ResNet_50 + Euclidean | 22.2% | 21.0% | 21.3% | 19.7% |
IDE_ResNet_50 + XQDA | 32.0% | 29.6% | 31.1% | 28.2% |
