Results on large popular datasets
| Dataset | Rank-1 | Rank-5 | Rank-10 | MAP |
|---|---|---|---|---|
| Market-1501 | 54.45 | 73.10 | 79.69 | 26.31 |
| DukeMTMC-reID | 40.26 | 57.59 | 64.09 | 19.81 |
CAMEL
In the folder ./CAMEL is the DEMO code on the Market-1501 dataset. Please see main.m for details.
Also note that a different MATLAB version may lead to a result that is a little bit different from the result reported in the paper, because of several random procedures in the algorithm and during the testing. The reported result (in this demo, 54.5% rank-1 accuracy for Market-1501) was obtained using MATLAB R2014a.
We also prepared a supervised version of CAMEL in main_supervised.m, which runs much faster than CAMEL and can be a weak baseline in comparison with supervised models.
Feature
In the folder ./Feature is the code for feature extraction. Here we provide the pre-trained JSTL model (without fine-tune or domain guided dropout) to extract features for different datasets apart from the test ones. Note that the model was pre-trained using the full training set [4], i.e., VIPeR, CUHK01, CUHK03, PRID, 3DPeS, i-LIDS and Shinpuhkan.
Our implementation is based on matconvnet: https://github.com/vlfeat/matconvnet
ExMarket
In the folder ./ExMarket is the package which contains the MATLAB code for constructing the ExMarket Dataset and evaluation. To construct the ExMarket dataset, please follow the steps below:
-
Download the Market-1501 dataset [1] from http://www.liangzheng.org/Project/project_reid.html
-
Download the MARS dataset [2] from http://www.liangzheng.org/Project/project_mars.html
-
Unzip them to the same directory with IMDBmaking.m, and run IMDBmaking.
If you use the dataset, please kindly cite [1] and [2] and our paper [3].
We also provide a demo for evaluation in main.m. The example feature ''ExMarket_JSTL64.mat'' was extracted using the JSTL model provided in ./Feature [4]. If you use the feature or the model, please also kindly cite [4].
