KAIST Multispectral Pedestrian Detection Benchmark
Leaderboard
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].

Integrity Verification
To ensure your download is complete and hasn’t been corrupted, we provide an MD5 checksum file.
1. Download MD5 file
You can download the checksum file along with the dataset:
- Preview set (kaist-cvpr15-preview.tar)
gdown 1nJkdnSI9fAuhhZPKFfhVXimXGzvuRTb6 - Full set (kaist-cvpr15.tar)
gdown 1KQ9lZXX9nfZuhbqBUEdlU2Yjx3nzeg5c
2. Verify Automatically (Recommended)
If you have both kaist-cvpr15.tar and kaist-cvpr15.tar.md5 in the same directory, run the following command:
- Linux / WSL:
md5sum -c kaist-cvpr15.tar.md5 - macOS:
# Check manually or use md5sum (if installed via brew) FILE="kaist-cvpr15.tar"; md5 -q $FILE | grep -qf - $FILE.md5 && echo "$FILE: OK"

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.
All the modifications are in libs/.
