This repository contains code for CVPR2023 paper:

Shuting He, Henghui Ding, Wei Jiang

framework

Installation:

The code is tested under CUDA 11.2, Pytorch 1.9.0 and Detectron2 0.6.

  1. Install Detectron2 following the manual
  2. Run sh make.sh under PADing/modeling/pixel_decoder/ops (Note: 1-2 steps you can also follow the installation process of Mask2Former)
  3. Install other required packages: pip install -r requirements.txt
  4. Prepare the dataset following datasets/README.md

Inference

CUDA_VISIBLE_DEVICES=0 python train_net.py \
    --config-file configs/panoptic-segmentation/PADing.yaml \
    --num-gpus 1 --eval-only \
    MODEL.WEIGHTS [path_to_weights] \
    OUTPUT_DIR [output_dir]

Training

Firstly, download the pretrained weights here or you can train vanilla mask2former backbone using seen classes and convert it using the following command:

python train_net_pretrain.py --config-file configs/panoptic-segmentation/pretrain.yaml --num-gpus 8

python tools/preprocess_pretrained_weight.py --task_name panoptic --input_file panoptic_pretrain/model_final.pth

Then train PADing and finetune the last class embedding layer of the trained mask2former model:

CUDA_VISIBLE_DEVICES=0 python train_net.py  --config-file configs/panoptic-segmentation/PADing.yaml --num-gpus 1 MODEL.WEIGHTS pretrained_weight_panoptic.pth

Trained Models and logs

Download pretrained weights here.

Download final trained PADing weights for inference here.

Semantic-segmentation Instance-segmentation Panoptic-segmentation
Seen | Unseen (IoU) Seen | Unseen (mAP) PQs, SQs, RQs | PQu,SQu,RQu
40.6 | 26.4 53.1 | 8.5 37.7/79.0/44.8 | 14.4/75.3/17.4

Note: We reorganize code and the performances are slightly different from the paper's.
