Overview

QSORT

QSORT(Quick + Simple Online and Realtime Tracking) is a simple online and realtime tracking algorithm for 2D multiple object tracking in video sequences. It is much faster than SORT(Simple Online and Realtime Tracking). But its performance is a little worse than SORT.

This method and project are heavily based on abewley/sort.

Note: A significant proportion of QSORT's accuracy is attributed to the detections. For your convenience, this repo also contains Faster RCNN detections for the MOT benchmark sequences in the benchmark format. To run the detector yourself please see the original Faster RCNN project or the python reimplementation of py-faster-rcnn by Ross Girshick.

What is different from SORT?

QSORT is SORT skipping the Kalman Filter. That's it.

Dependencies:

To install required dependencies run:

pip install -r requirements.txt

Demo:

To run the tracker with the provided detections:

cd path/to/qsort
python qsort.py

To display the results you need to:

Download the 2D MOT 2015 benchmark dataset and unzip this file.
Create a symbolic link to the dataset

ln -s /path/to/MOT15 MOT15

Run the demo with the --display flag

python qsort.py --display

Main Results

Using the MOT challenge devkit the method produces the following results (as described in the paper).

Method	MOTA	IDs	FPS
SORT	34.0	274	742
QSORT	31.7	344	2194

Sequence: TUD-Campus, ETH-Sunnyday, ETH-Pedcross2, ADL-Rundle-8, Venice-2, and KITTI-17
MOTA, FPS: Higher is better.
IDs: Lower is better.

FPS is measured on a Intel I5 10400 CPU.

Using QSORT in your own project

Below is the gist of how to instantiate and update QSORT. See the 'main' section of qsort.py for a complete example.

from qsort import *

#create instance of QSORT
mot_tracker = QSORT() 

# get detections
...

# update QSORT
track_bbs_ids = mot_tracker.update(detections)

# track_bbs_ids is a np array where each row contains a valid bounding box and track_id (last column)
...

Why is QSORT faster than SORT?

Hello, I am curious to know what improvements you made to SORT. What details make QSORT so much faster than SORT?

Thank you

Update: nevermind, I see on the README that it skips the kalman filter.

If you need the simplest, fastest tracker, I recommend IOU tracker https://github.com/bochinski/iou-tracker. In my practical use, I found it 20x faster than SORT.
