TransDETR: End-to-end Video Text Spotting with Transformer

Introduction

End-to-end Video Text Spotting with Transformer | Youtube Demo

Video text spotting(VTS) is the task that requires simultaneously detecting, tracking and recognizing text instances in video. Recent methods typically develop sophisticated pipelines based on Intersection over Union (IoU) or appearance similarity in adjacent frames to tackle this task. In this paper, rooted in Transformer sequence modeling, we propose a novel video text DEtection, Tracking, and Recognition framework (TransDETR), which views the VTS task as a direct long-sequence temporal modeling problem.

• We use the models pre-trained on COCOTextV2.
• We do not release the recognition code due to the company's regulations.

Demo

Installation

The codebases are built on top of Deformable DETR and MOTR.

• Linux, CUDA>=9.2, GCC>=5.4

• Python>=3.7

  We recommend you to use Anaconda to create a conda environment:

  conda create -n TransDETR python=3.7 pip

  Then, activate the environment:

  conda activate TransDETR

• PyTorch>=1.5.1, torchvision>=0.6.1 (following instructions here)

  For example, if your CUDA version is 9.2, you could install pytorch and torchvision as following:

  conda install pytorch=1.5.1 torchvision=0.6.1 cudatoolkit=9.2 -c pytorch

• Other requirements

  pip install -r requirements.txt

• Build MultiScaleDeformableAttention and Rotated ROIAlign

  cd ./models/ops
  sh ./make.sh
  
  cd ./models/Rotated_ROIAlign
  python setup.py build_ext --inplace

Usage

Dataset preparation

1. Please download ICDAR2015, COCOTextV2 dataset, DSText](https://rrc.cvc.uab.es/?ch=22&com=downloads) and organize them like FairMOT as following:

Firstly, after downloading the video data, you can use ExtractFrame_FromVideo.py to extract frames, and copy the frames to images path. labels_with_ids path is automatically generated by the generation script in tools/gen_labels.

./Data
    ├── COCOText
    │   ├── images
    │   └── labels_with_ids
    ├── ICDAR15
    │   ├── images
    │       ├── track
    │           ├── train
                    ├──Video_10_1_1
                        ├──1.jpg
                        ├──2.jpg
                    ├──Video_13_4_1

2. You also can use the following script to generate txt file:

cd tools/gen_labels
python3 gen_labels_COCOTextV2.py
python3 gen_labels_15.py
python3 gen_labels_YVT.py
cd ../../

(These scripts are mainly intended to accomplish two tasks: 1) Generate the ground truth in the labels_with_ids path. 2) Generate the corresponding training image list (*.txt) for each dataset's training set in the ./datasets/data_path.)

Note: Before running the corresponding script, you need to modify the paths in the .py file to your own paths. Specifically, you should modify the following paths:

• from_label_root: the path of the original ground truth data (e.g., the path to the .xml files for ICDAR15).
• seq_root: the path of the video frames.
• label_root: the path to generate the annotations. Finally, when running the gen_data_path function to generate the training image list (*.txt), modify the path accordingly.

Training and Evaluation

Training on single node

Before training, you need to modify the following paths in the .sh file: mot_path: your data path (e.g., ./Data). data_txt_path_train: the training image list file (.txt) that was generated during the data preparation. Please update these paths to match your specific setup.

You can download COCOTextV2 pretrained weights for Pretrained TransDETR Google Drive. Or training by youself:

sh configs/r50_TransDETR_pretrain_COCOText.sh

Then training on ICDAR2015 with 8 GPUs as following:

sh configs/r50_TransDETR_train_ICDAR15video.sh

Or training on DSText with 8 GPUs as following:

sh configs/r50_TransDETR_train_DSText.sh

Evaluation on ICDAR13 and ICDAR15

You can download the pretrained model of TransDETR (the link is in "Main Results" session), then run following command to evaluate it on ICDAR2015 dataset:

sh configs/r50_TransDETR_eval_ICDAR2015.sh

evaluate on ICDAR13

python tools/Evaluation_ICDAR13/evaluation.py --groundtruths "./tools/Evaluation_ICDAR13/gt" --tests "./exps/e2e_TransVTS_r50_ICDAR15/jons"

evaluate on ICDAR15

cd exps/e2e_TransVTS_r50_ICDAR15
zip -r preds.zip ./preds/*

then submit to the ICDAR2015 online metric

Evaluation on DSText

Inference , we also provide the trained weight on Google drive

sh configs/r50_TransDETR_eval_BOVText.sh

Then zip the result file and submit to the DSText online metric

cd exps/e2e_TransVTS_r50_DSText/preds
zip -r ../preds.zip ./*

Visualization

For visual in demo video, you can enable 'vis=True' in eval.py like:

--show

then run the script:

python tools/vis.py
