OMC tutorial

We assume the root path is $OMC, e.g. /home/chaoliang/MOT

Set up environment

$conda_path denotes your anaconda path, e.g. /home/chaoliang/anaconda3

conda create -n OMC python=3.8
source activate OMC
cd OMC/lib/tutorial/
pip install -r requirements.txt

Testing

Prepare data and models

  1. Download the testing model [[Google Drive]]https://drive.google.com/drive/folders/1lG-bwk22uJjUw5DBy92-h857qMXKJ1Ba?usp=sharing)[[Baidu NetDisk(omct)]](https://pan.baidu.com/s/1mqEFjZJ4Cz00Zy9erl7auw) to $SOTS/model.
  2. Download testing data e.g. MOT-16 and put them in $SOTS/dataset. The dataset can be downloaded from their official webpage.

Inference

In root path $OMC/tracking,

For MOT-16

python test_omc.py --weights ../model/OMC_mot17.pt 
				   --cfg ../experiments/model_set/CSTrack_l.yaml 
				   --name l-mot16-test 
				   --test_mot16 True 
				   --output_root runs/test_w_recheck

For MOT-17

python test_omc.py --weights ../model/OMC_mot17.pt 
				   --cfg ../experiments/model_set/CSTrack_l.yaml 
				   --name l-mot17-test 
				   --test_mot17 True 
				   --output_root runs/test_w_recheck

For MOT-20

python test_omc.py --weights ../model/OMC_mot20.pt 
                   --cfg ../experiments/model_set/CSTrack_l.yaml 
                   --name l-mot20-test 
                   --test_mot20 True 
                   --output_root runs/test_w_recheck
  • Note: If you want to test the performance of the model. Please sign up at MOT challange and test it.

Training

Prepare data and models

  1. Download the pretrained model which pretrain in COCO dataset [Google Drive][Baidu NetDisk(omct)] to $SOTS/weights.

  2. We provide several relevant datasets for training and evaluating the CSTrack. Annotations are provided in a unified format and all the datasets have the following structure:

Caltech
   |——————images
   |        └——————00001.jpg
   |        |—————— ...
   |        └——————0000N.jpg
   └——————labels_with_ids
            └——————00001.txt
            |—————— ...
            └——————0000N.txt

Every image has a corresponding annotation text. Given an image path, the annotation text path can be generated by replacing the string images with labels_with_ids and replacing .jpg with .txt.

In the annotation text, each line is describing a bounding box and has the following format:

[class] [identity] [x_center] [y_center] [width] [height]

The field [class] should be 0. Only single-class multi-object tracking is supported in this version.

The field [identity] is an integer from 0 to num_identities - 1, or -1 if this box has no identity annotation.

*Note that the values of [x_center] [y_center] [width] [height] are normalized by the width/height of the image, so they are floating point numbers ranging from 0 to 1.

The datasets including Caltech, CityPersons, CUHK-SYSU, PRW, ETHZ and MOT-17 follow JDE.
