Overview

We release the code for our paper in CVPR 2021. For more information please refer to our accepted paper in CVPR 2021.

Project Download

Firstly please download the project through:

git clone https://github.com/uark-cviu/DyGLIP

Prerequisites

The code requires the following libraries to be installed:

• [Python] (https://python.org/) 3.6+
• PyTorch >= 1.5
• [CUDA] (https://developer.nvidia.com/cuda-downloads) 9.0+

cd DyGLIP
conda env create -f environment.yml 
conda activate dyglip

Step 1 - Detection

Please follow detection guidance to get bounding boxes prediction.

Get maskrcnn features by running the file Step1_Detection/identifier/preprocess/extract_img_and_feat.py, the output should be two files: bboxes.pkl and maskrcnn_feats.pkl.

Get pre-computed reid features by running the file Step1_Detection/identifier/preprocess/extract_img_and_reid_feat.py, the output should be the reid_feats.pkl file.

Step 2 - Graph-based Feature Extraction

This environment must be python 2.7, tensorflow 1.11

Prepare graph Step2_GraphFeature/prepare_graphs.py

Please follow GraphFeature guidance to train the model.

Step 3 - Matching

Get output from matching baselines graph and non-negative matrix factorization.
