KAIST Multispectral Pedestrian Detection Benchmark

News (10/07/2021)

Due to the confusion caused by original paper, people sometimes reported numbers in different evaluation settings. In this regard, people from Sejong University(Jiwon Kim, Hyeongjun Kim, Tae-Joo Kim and Yukyung Choi) created a leaderboard to facilitate fair comparison. So please use this leaderboard for your research.

Introduction

By Soonmin Hwang, Jaesik Park, Namil Kim, Yukyung Choi, In So Kweon at RCV Lab. (KAIST) [Website]

We developed imaging hardware consisting of a color camera, a thermal camera and a beam splitter to capture the aligned multispectral (RGB color + Thermal) images. With this hardware, we captured various regular traffic scenes at day and night time to consider changes in light conditions.

The KAIST Multispectral Pedestrian Dataset consists of 95k color-thermal pairs (640x480, 20Hz) taken from a vehicle. All the pairs are manually annotated (person, people, cyclist) for the total of 103,128 dense annotations and 1,182 unique pedestrians. The annotation includes temporal correspondence between bounding boxes like Caltech Pedestrian Dataset. More infomation can be found in our CVPR 2015 [paper] [Ext. Abstract].

Usage

1. Clone this repository.

git clone --recursive https://github.com/soonminhwang/rgbt-ped-detection

1. First, download multispectral dataset.

cd rgbt-ped-detection/data/scripts
chmod +x fetch_dataset_kaist_cvpr15.py & ./fetch_dataset_kaist_cvpr15.py & cd ../../

or

fetch_dataset_kaist_cvpr15.m

in MATLAB.

1. Altenatively, you can get direct links for the dataset here.

2. Then just run

Toolbox

This repository includes an extension of Piotr's Computer Vision Matlab Toolbox. We modify some codes to deal with 4-ch RGB+T images, e.g.

${PIOTR_TOOLBOX}/channels/chnsCompute.m

Many researchers struggle to improve pedestrian detection performance on our benchmark. If you are interested, please see these works.

• FusionRPN + BDT [CVPR '17]: 29.83%
• Halfway Fusion [BMVC '16]: 36.22%
• LateFusion CNN [ESANN '16]: 43.80%
• CMT-CNN [CVPR '17]: 49.55%
• Baseline, ACF+T+THOG [CVPR '15]: 54.40%

Also, another researches to employ multi-modality are presented.
