#Unsupervised Salience Learning for Person Re-identification

MATLAB code for our CVPR 2013 work "R. Zhao, W. Ouyang, and X. Wang. Unsupervised Salience Learning for Person Re-identification. In CVPR 2013."

Created by Rui Zhao, on May 20, 2013.

##Summary In this package, you find an updated version of MATLAB code for the following paper: Rui Zhao, Wanli Ouyang, and Xiaogang Wang. Unsupervised Salience Learning for Person Re-identification. In IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2013.

##Install

Download VIPeR dataset, and put the subfolders (\cam_a and \cam_b) into directory .\dataset\viper\
Download ETHZ dataset, and put the subfolders (\seq1, \seq2, and \seq3) into directory .\dataset\ethz\
Compile patchmatch component: go to directory ./code/patchmatch and run mex *.cpp in Matlab
Compile LibSVM: go to directory ./code/libsvm, and run make.m in Matlab
If you are running on Linux or OS X system, slash characters in following files should be changed from '' to '/' accordingly: ./code/norm_data.m, ./code/initialcontext_general.m, ./set_paths.m, ./demo_salience_reid_viper.m, ./demo_salience_reid_ethz.m

##Demos Two demos are available for reproducing the results.

demo_salience_reid_viper.m : perform evaluation over VIPeR dataset
demo_salience_reid_ethz.m : perform evaluation over ETHZ dataset (including Seq.1, Seq.2, and Seq.3).

##Remarks

This implementation is a little different than the original version in the training / testing partition, so that the result may vary a little, if you use the default settings and parameters, you are supposed to obtain the rank-1 matching rate for the trial 1 on VIPeR dataset: 25.32% (SDC_knn) and 27.22% (SDC_ocsvm).
The training / testing partition is generated following the approach SDALF
Parallel Toolbox can accellerate the computation, use matlabpool if necessary
This demo was tested on MATLAB (R2010b), 64-bit Win7, Intel Xeon 3.30 GHz CPU
Memory cost:
- Running demo on VIPeR dataset would consume around 1.0 GB memory
  - Running demo on ETHZ (seq1) dataset would consume around 5.0 GB memory
  - Running demo on ETHZ (seq2) dataset would consume around 1.6 GB memory
  - Running demo on ETHZ (seq3) dataset would consume around 1.4 GB memory

##Additional Libs We provide with our package some additional libraries we used in our implementation.

svmtrain.mexw64 in LibSVM, http://www.csie.ntu.edu.tw/~cjlin/libsvm/
slmetric_pw.m in sltoolbox, http://www.mathworks.com/matlabcentral/fileexchange/12333-statistical-learning-toolbox
dense feature in Scenes/Objects classification toolbox, http://www.mathworks.com/matlabcentral/fileexchange/29800-scenesobjects-classification-toolbox/content/reco_toolbox/html/demo_denseSIFT.html Please note that the dense features codes have been heavily re-written for modification flexibility.
