Introduction

Code for 2016 TPAMI(IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE) A Comprehensive Study on Cross-View Gait Based Human Identification with Deep CNNs

Data

Prepare the dataset

get gait dataset from http://www.am.sanken.osaka-u.ac.jp/BiometricDB/GaitLP.html, use the Version 1, OULP-C1V1, http://www.am.sanken.osaka-u.ac.jp/BiometricDB/doc/OULP_Doc01a_SubsetStatistics_OULP-C1V1.pdf, download the dataset into path: ~/data/, rename the directory to OULP_C1V1_Pack, you can see directories OULP-C1V1_NormalizedSilhouette(88x128) and OULP-C1V1_SubjectIDList(FormatVersion1.0) in ~/data/OULP_C1V1_Pack.

Prepare training, validation and test dataset

protocol, described in paper: Cross-View Gait Recognition Using View-Dependent Discriminative Analysis. In this experiments, training set described in the paper was split into traning and validation part, in OULP_setting/list_train.txt and OULP_setting/list_val.txt

change current directory to here
move OULP_setting directory to ~/data/OULP_setting, run command line: cp -r OULP_setting ~/data/OULP_setting
run command line:python preprocess_script/oulp_prepare.py ~/data/gait-oulp-c1v1

Running the code

Command line example to run the code

th main.lua -datapath ~/data/gait-oulp-c1v1 -mode train  -modelname wuzifeng -gpu -gpudevice 1  -dropout 0.5 -learningrate 1e-3 -momentum 0.9 -calprecision 2 -calval 1 -batchsize 64 -iteration 2000000 >> main.lua.log

Result

you will see the validation average precision up to 92.50.

you will see results in main.lua.log which like below:

  iteration : 2000000
  seed : 1

Test

select the model file in trainedNet as a argument of -loadmodel when run main.lua, then you can see the test result in the redirected file. the best average recognition precision you can get is 88.29.

th main.lua -datapath ~/data/gait-oulp-c1v1 -mode evaluate -datapart test  -modelname wuzifeng -gpu -gpudevice 1 -loadmodel ./trainedNets/wuzifeng_tra_0.6666_i7745.t7 >> main.lua.result.log
