  • We provide another version based on MindSpore

Installation

Please find installation instructions in INSTALL.md.

Quick Start: Using HDN

Add HDN to your PYTHONPATH

vim ~/.bashrc
# add home of project to PYTHONPATH
export PYTHONPATH=/path/to/HDN:/path/to/HDN/homo_estimator/Deep_homography/Oneline_DLTv1:$PYTHONPATH

Download models

Google Drive or Baidu Netdisk (key: 8uhq)

Base Setting

The global parameters setting file is hdn/core/config.py You first need to set the base path:

__C.BASE.PROJ_PATH = /xxx/xxx/project_root/ #/home/Kay/SOT/server_86/HDN/   (path_to_hdn)
__C.BASE.BASE_PATH = /xxx/xxx/ #/home/Kay/SOT/                  (base_path_to_workspace)
__C.BASE.DATA_PATH = /xxx/xxx/data/POT  #/home/Kay/data/POT     (path to POT datasets)
__C.BASE.DATA_ROOT = /xxx/xxx   #/home/Kay/Data/Dataset/        (path to other datasets)

Demo

Planar Object Tracking and its applications

we provide 4 modes:

  • tracking: tracking planar object with not less than 4 points in the object.
  • img_replace: replacing planar object with image .
  • video_replace: replacing planar object with video.
  • mosiac: adding mosiac to planar object.
python tools/demo.py 
--snapshot model/hdn-simi-sup-hm-unsup.pth 
--config experiments/tracker_homo_config/proj_e2e_GOT_unconstrained_v2.yaml 
--video demo/door.mp4 
--mode img_replace 
--img_insert demo/coke2.jpg #required in mode 'img_replace'  
--video_insert demo/t5_videos/replace-video/   #required in mode 'video_replace'
--save # whether save the results.

e.g.

python tools/demo.py  --snapshot model/hdn-simi-sup-hm-unsup.pth  --config experiments/tracker_homo_config/proj_e2e_GOT_unconstrained_v2.yaml --video demo/door.mp4 --mode img_replace --img_insert demo/coke2.jpg --save

we provide some real-world videos here

Download testing datasets

POT

For POT dataset, download the videos from POT280 and annotations from here

1. unzip POT_v.zip and POT_annotation.zip and put them in your cfg.BASE.DATA_PATH #unzip the zip files
  cd POT_v
  unzip "*.zip"
  cd ..

2. mkdir POT
   mkdir path_to_hdn/testing_dataset
   python path_to_hdn/toolkit/benchmarks/POT/pot_video_to_pic.py #video to images  
   ln -s path_to_data/POT  path_to_hdn/testing_dataset/POT #link to testing_datasets


4. python path_to_hdn/toolkit/benchmarks/POT/generate_json_for_POT.py --dataset POT210 #generate json annotation for POT
   python path_to_hdn/toolkit/benchmarks/POT/generate_json_for_POT.py --dataset POT280

UCSB & POIC

Download from here put them in your cfg.BASE.DATA_PATH

ln -s path_to_data/UCSB  path_to_hdn/testing_dataset/UCSB #link to testing_datasets

generate json:

  python path_to_hdn/toolkit/benchmarks/POIC/generate_json_for_poic.py #generate json annotation for POT
  python path_to_hdn/toolkit/benchmarks/UCSB/generate_json_for_ucsb.py #generate json annotation for POT

Other datsets:

Download datasets and put them into testing_dataset directory. Jsons of commonly used datasets can be downloaded from here. If you want to test tracker on new dataset, please refer to pysot-toolkit to setting testing_dataset.

Test tracker

  • test POT
cd experiments/tracker_homo_config
python -u ../../tools/test.py \
	--snapshot ../../model/hdn-simi-sup-hm-unsup.pth \ # model path 
	--dataset POT210 \ # dataset name
	--config proj_e2e_GOT_unconstrained_v2.yaml # config file
	--vis   #display video

The testing results will in the current directory(./results/dataset/model_name/)

Eval tracker

For POT evaluation

1.use tools/change_pot_results_name.py to convert result_name(you need to set the path in the file).

2.use tools/convert2Homography.py to generate the homo file(you need to set the corresponding path in the file).

3.use POT toolkit to test the results. My version toolkit can be found here or official for other trackers:

For others:

For POIC, UCSB or POT evaluation on centroid precision, success rate, and robustness etc. assuming still in experiments/tracker_homo_config

python ../../tools/eval.py 	 \
	--tracker_path ./results \ # result path
	--dataset POIC        \ # dataset name
	--num 1 		 \ # number thread to eval
	--tracker_prefix 'model'   # tracker_name

The raw results can be downloaded at Google Drive or Baidu Netdisk (key:d98h)

Training 🔧

We use the COCO14 and GOT10K as our traning datasets. See TRAIN.md for detailed instruction.
