Requirements

• python 2.7
• pytorch 0.3.1
• MARS, iLIDS or other datasets.

Training

Prepare Datasets

1. File Directory: ├── partitions.pkl ├── images │ ├── 0000000_0000_000000.png │ ├── 0000001_0000_000001.png │ ├── ...

2. Rename the images in following convention: "000000_000_000000.png" where the first substring splitted by underline is the person identity; for the second substring, the first digit is the camera id and the rest is track id; and the third substring is an image offset.

3. "partitions.pkl" file This file contains a python dictionary storing meta data of the datasets, which contains folling key value pairs "train_im_names": [list of image names] #storing a list of names of training images "train_ids2labels":{"identity":label} #a map that maps the person identity string to a integer label "val_im_names": [list of image names] #storing a list of names of validation images "test_im_names": [list of image names] #storing a list of names of testing images "test_marks"/"val_marks": [list of 0/1] #0/1 indicates if an image is in gallery

4. Other dataset directory structure To use other directory structure, override the data loader in "stf/Dataset/dataset.py"
