Prerequisites

• Python 3.7
• PyTorch 1.1
• CUDA 10.2

Dataset & Preparation

Download OU-MVLP Dataset.

!!! ATTENTION !!! ATTENTION !!! ATTENTION !!!

Before training or test, please make sure you have prepared the dataset by this two steps:

• Step1: Organize the directory as: your_dataset_path/subject_ids/walking_conditions/views. E.g. OUMVLP/00001/00/000/.
• Step2: Cut and align the raw silhouettes with pretreatment_oumvlp.py. the silhouettes after pretreatment MUST have a size of 64x64.

Pretreatment

pretreatment_oumvlp.py uses the alignment method in this paper. Pretreatment your dataset by

python pretreatment_oumvlp.py --input_path='root_path_of_raw_dataset' --output_path='root_path_for_output'

• --input_path (NECESSARY) Root path of raw dataset.
• --output_path (NECESSARY) Root path for output.
• --log_file Log file path. #Default: './pretreatment.log'
• --log If set as True, all logs will be saved. Otherwise, only warnings and errors will be saved. #Default: False
• --worker_num How many subprocesses to use for data pretreatment. Default: 1

Train

Train a model by

python train.py

'batch_size': (32, 8), 'frame_num': 30, 'total_iter': 250000.The learning rate is 1e − 4 in the first 150K iterations, and then is changed into 1e − 5 for the rest of 100K iterations.

• --cache if set as TRUE all the training data will be loaded at once before the training start. This will accelerate the training. Note that if this arg is set as FALSE, samples will NOT be kept in the memory even they have been used in the former iterations. #Default: TRUE

Evaluation

Evaluate the trained model by

python test_oumvlp.py

• --iter iteration of the checkpoint to load. #Default: 250000
• --batch_size batch size of the parallel test. #Default: 1
• --cache if set as TRUE all the test data will be loaded at once before the transforming start. This might accelerate the testing. #Default: FALSE

CAISA-E

Dataset & Preparation

Function generate_test_gallery() generate_train_gallery() generate_test_probe() from pt_casiae.py

Train

OUMVLP Pre-training parameters need to be added. Train a model by

python train.py

'batch_size': (12, 8), 'frame_num': 64, 'total_iter': 15000. The learning rate is 1e − 4 in the first 10K iterations, and then is changed into 1e − 5 for the rest of 5K iterations.

Test

Training parameters. Test a model by using Function testout() from pt_casiae.py

python pt_casiae.py
