[CVPR2024] Traffic Scene Parsing through the TSP6K Dataset

demo.mp4

The dataset and code in TSP6K dataset. Code is implemented using an open-source semantic segmentation toolbox, MMsegmentation.

Installation

Please follow the installation instructions in mmsegmentation. In our environment, we use the following versions of different packages.

mmsegmentation==0.20.2
mmcv-full=1.4.0

Install the mmseg lib first

git clone https://github.com/PengtaoJiang/TSP6K.git
cd TSP6K/
pip install -v -e .

If you want to evaluate the iIoU score, please install the cityscapesscript lib

cd mmseg/datasets/cityscapesscripts/
python setup.py build install

Dataset Preparation

Download the dataset from this link and put them into /data/TSP6K/. Since the paper has not been accepted yet, you can successfully download the dataset once you have sent an email to (pt.jiang at mail.nankai.edu.cn) to obtain the password.

Training

Train SegNext with the proposed Detail Refining Decoder using the following command

bash tools/dist_train.sh \
configs/tsp6k/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads.py \
8 --auto-resume  

Evaluation

Results and models

Method	Backbone	Crop Size	Lr Sche.	val mIoU (ms)	val iIoU (ms)	config	model
SegNext+DRD	MSCAN-B	1024x1024	160000	75.8	58.4	config	model
SegNext+DRD	MSCAN-L	1024x1024	160000	76.2	58.9	config	model

We provide the pre-trained segmentation models above. You can download them and directly evaluate them by

bash tools/dist_test.sh \
    configs/tsp6k/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads.py \
    ./work_dirs/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads/latest.pth \
    8 --out ./work_dirs/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads/results.pkl \
    --aug-test --eval mIoU  

Evaluate the segmentation model using the iIoU metric by

bash tools/dist_test.sh \
    configs/tsp6k/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads.py \
    ./work_dirs/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads/latest.pth \
    8 --out ./work_dirs/segnext_base_1024x1024_160k_tsp6k_msaspp_rrm_5tokens_12heads/results.pkl \
    --aug-test --eval cityscapes
