UVLTrack

The official implementation of our AAAI 2024 paper Unifying Visual and Vision-Language Tracking via Contrastive Learning

Brief Introduction

Single object tracking aims to locate the target object in a video sequence according to the state specified by different modal references, including the initial bounding box (BBOX), natural language (NL), or both (NL+BBOX). Different previous modality-specific trackers, we present a unified tracker called UVLTrack, which can simultaneously handle all three reference settings (BBOX, NL, NL+BBOX) with the same parameters, allowing wider appliation scenarios. The proposed UVLTrack enjoys several merits. First, we design a modality-unified feature extractor for joint visual and language feature learning and propose a multi-modal contrastive loss to align the visual and language features into a unified semantic space. Second, a modality-adaptive box head is proposed, which makes full use of the target reference to mine ever-changing scenario features dynamically from video contexts and distinguish the target in a contrastive way, enabling robust performance in different reference settings.

Strong Performance

UVLTrack presents strong performance under different reference settings.

Install the environment

Use the Anaconda

conda env create -f uvltrack_env.yaml

or

conda create -n uvltrack python=3.6
conda activate uvltrack
bash install.sh

Data Preparation

Put the tracking datasets in ./data. It should look like:

${UVLTrack_ROOT}

         |-- airplane
         |-- basketball
         |-- bear

Train UVLTrack

Download the pretrained MAE and BERT, put it under <PROJECT_ROOT>/pretrain.

Training with multiple GPUs using DDP.

# UVLTrack
sh scripts/train.sh uvltrack baseline_base

Evaluation

Download the model weight from Google Drive or Baidu Netdisk.

Put the downloaded weights on <PROJECT_ROOT>/checkpoints/train/uvltrack/baseline_base and <PROJECT_ROOT>/checkpoints/train/uvltrack/baseline_large correspondingly.

Notably, the modality of target reference (NL, BBOX or NLBBOX) is specified in config TEST.MODE

# Testing
sh scripts/test.sh uvltrack baseline_base <dataset_name> <num_threads_per_gpu> <num_gpu>

# Evaluation
python tracking/analysis_results.py --tracker_name uvltrack --tracker_param baseline_base --dataset_name <dataset_name>_<reference_modality>_<EPOCH>

# Example
sh scripts/test.sh uvltrack baseline_base otb99 4 2
python tracking/analysis_results.py --tracker_name uvltrack --tracker_param baseline_base --dataset_name otb99_NL_300

Run UVLTrack on your own video

Specify the target by bounding box or natural language, which should keep consistent with TEST.MODE in config.

sh scripts/demo.sh uvltrack baseline_base \
                   <input video path> \
                   <output video path> \
                   <language description of target> \
                   <initial bbox of target: x y w h>

Test Speed

# UVLTrack-B: About 60 FPS on NVIDIA RTX 3090 GPU
python tracking/profile_model.py --script uvltrack --config baseline_base
# UVLTrack-L: About 34 FPS on NVIDIA RTX 3090 GPU
python tracking/profile_model.py --script uvltrack --config baseline_large
