🎯 Abstract

Tracking using bio-inspired event cameras draws more and more attention in recent years. Existing works either utilize aligned RGB and event data for accurate tracking or directly learn an event-based tracker. The first category needs more cost for inference and the second one may be easily influenced by noisy events or sparse spatial resolution. In this paper, we propose a novel hierarchical knowledge distillation framework that can fully utilize multi-modal / multi-view information during training to facilitate knowledge transfer, enabling us to achieve high-speed and low-latency visual tracking during testing by using only event signals. Specifically, a teacher Transformer based multi-modal tracking framework is first trained by feeding the RGB frame and event stream simultaneously. Then, we design a new hierarchical knowledge distillation strategy which includes pairwise similarity, feature representation and response maps based knowledge distillation to guide the learning of the student Transformer network. Moreover, since existing event-based tracking datasets are all low-resolution ($346 \times 260$), we propose the first large-scale high-resolution ($1280 \times 720$) dataset named EventVOT. It contains 1141 videos and covers a wide range of categories such as pedestrians, vehicles, UAVs, ping pongs, etc. Extensive experiments on both low-resolution (FE240hz, VisEvent, COESOT), and our newly proposed high-resolution EventVOT dataset fully validated the effectiveness of our proposed method.

🔨 Environment

A distillation framework for Event Stream-based Visual Object Tracking.

[HDETrack_S_ep0050.pth] Passcode：wsad

[Raw Results] Passcode：wsad

Install env

conda create -n hdetrack python=3.8
conda activate hdetrack
bash install.sh

Run the following command to set paths for this project

python tracking/create_default_local_file.py --workspace_dir . --data_dir ./data --save_dir ./output

After running this command, you can also modify paths by editing these two files

lib/train/admin/local.py  # paths about training
lib/test/evaluation/local.py  # paths about testing

Then, put the tracking datasets EventVOT in ./data.

Download pre-trained MAE ViT-Base weights and put it under $/pretrained_models

Download teacher pre-trained CEUTrack_ep0050.pth and put it under $/pretrained_models

Download the trained model weights from [HDETrack_S_ep0050.pth] and put it under $/output/checkpoints/train/hdetrack/hdetrack_eventvot for test directly.

You can also access Weight files in Dropbox to download these weights files.

Train & Test

# train
python tracking/train.py --script hdetrack --config hdetrack_eventvot --save_dir ./output --mode single --nproc_per_node 1 --use_wandb 0

Normally, we only need the "img" and "..._voxel" files from the EventVOT dataset for training. During testing, we only input "img" for inference. As shown in the following figure,

Note: Our EventVOT dataset is an unimodal Event Dataset, if you need a multimodal RGB-E dataset, please refer to [COESOT]， [VisEvent], or [FELT].
