The website of our lab sometime got closed for some political reason, the attributes dataset can also be downlowded BaiduYun(passwd:beda) OR GoogleDrive

video_pedestrian_attributes_recognition

Codes for the paper "A Temporal Attentive Approach for Video-Based Pedestrian Attribute Recognition".

Introduction

This repository contains PyTorch implementations of temporal modeling methods for video-based pedestrian attributes recognition. It is forked from Video-Person-ReID. Based on that, I implement temporal modeling methods including temporal pooling, temporal attention, RNN and 3D conv for multi-attributes recognition. PyTorch 0.4.1, Torchvision 0.2.1 and Python 3.7 is used.

Motivation

Although previous work proposed many temporal modeling methods and did extensive experiments, but it's still hard for us to have an "apple-to-apple" comparison across these methods. As the image-level feature extractor and loss function are not the same, which have large impact on the final performance. Thus, we want to test the representative methods under an uniform framework.

Dataset

Experiments are done on MARS.

Please follow deep-person-reid to prepare the data. The instructions are copied here:

Create a directory named mars/ under data/.
Download dataset to data/mars/ from http://www.liangzheng.com.cn/Project/project_mars.html.
Extract bbox_train.zip and bbox_test.zip.
Download split information from https://github.com/liangzheng06/MARS-evaluation/tree/master/info and put info/ in data/mars (we want to follow the standard split in [8]).
Download mars_attributes.csv from http://irip.buaa.edu.cn/mars_duke_attributes/index.html, and put the file in data/mars. The data structure would look like:
```
mars/
bbox_test/
bbox_train/
info/
mars_attributes.csv
```
Use -d mars when running the training code.

Experiments are done on Duke.

Create a directory named duke/ under data/.
Download dataset to data/duke/ from http://vision.cs.duke.edu/DukeMTMC/data/misc/DukeMTMC-VideoReID.zip.
Extract DukeMTMC-VideoReID.zip.
Download duke_attributes.csv from http://irip.buaa.edu.cn/mars_duke_attributes/index.html, and put the file in data/duke. The data structure would look like:
```
duke/
train/
gallery/
query/
duke_attributes.csv
```
Use -d duke when running the training code.

Usage

To train the model, please run

python -u main_video_attr_recog.py --arch=attr_resnet50tp --model_type="ta"

arch could be Temporal Attention Method (--arch=attr_resnet50tp --model_type="ta"), Temporal Pooling Method (--arch=attr_resnet50tp --model_type="tp"), RNN Attention Method (--arch=attr_resnet50tp --model_type="rnn"), 3D conv (--arch=attr_resnet503d). For 3D conv, I use the design and implementation from 3D-ResNets-PyTorch, just minor modification is done to fit the network into this person attributes recognition system.

Other detailed settings for different temporal modeling could be found in models/AttrModels.py
