Overview

Vision Transformer for Fast and Efficient Scene Text Recognition (ICDAR 2021)

ViTSTR is a simple single-stage model that uses a pre-trained Vision Transformer (ViT) to perform Scene Text Recognition (ViTSTR). It has a comparable accuracy with state-of-the-art STR models although it uses significantly less number of parameters and FLOPS. ViTSTR is also fast due to the parallel computation inherent to ViT architecture.

Multi-GPU training

ViTSTR-Small on a 4-GPU machine

It is recommended to train larger networks like ViTSTR-Small and ViTSTR-Base on a multi-GPU machine. To keep a fixed batch size at 192, use the --batch_size option. Divide 192 by the number of GPUs. For example, to train ViTSTR-Small on a 4-GPU machine, this would be --batch_size=48.

python3 train.py --train_data data_lmdb_release/training 
--valid_data data_lmdb_release/evaluation --select_data MJ-ST 
--batch_ratio 0.5-0.5 --Transformation None --FeatureExtraction None 
--SequenceModeling None --Prediction None --Transformer 
--TransformerModel=vitstr_small_patch16_224 --imgH 224 --imgW 224 
--manualSeed=$RANDOM --sensitive --batch_size=48

Data augmentation

ViTSTR-Tiny using rand augment

It is recommended to use more workers (eg from default of 4, use 32 instead) since the data augmentation process is CPU intensive. In determining the number of workers, a simple rule of thumb to follow is it can be set to a value between 25% to 50% of the total number of CPU cores. For example, for a system with 64 CPU cores, the number of workers can be set to 32 to use 50% of all cores. For multi-GPU systems, the number of workers must be divided by the number of GPUs. For example, for 32 workers in a 4-GPU system, --workers=8. For convenience, simply use --workers=-1, 50% of all cores will be used. Lastly, instead of using a constant learning rate, a cosine scheduler improves the performance of the model during training.

Below is a sample configuration for a 4-GPU system using batch size of 192.

python3 train.py --train_data data_lmdb_release/training
--valid_data data_lmdb_release/evaluation --select_data MJ-ST 
--batch_ratio 0.5-0.5 --Transformation None --FeatureExtraction None 
--SequenceModeling None --Prediction None --Transformer 
--TransformerModel=vitstr_tiny_patch16_224 --imgH 224 --imgW 224 
--manualSeed=$RANDOM  --sensitive
--batch_size=48 --isrand_aug --workers=-1 --scheduler

What Is Wrong With Scene Text Recognition Model Comparisons? Dataset and Model Analysis

| paper | training and evaluation data | failure cases and cleansed label | pretrained model | Baidu ver(passwd:rryk) |

Official PyTorch implementation of our four-stage STR framework, that most existing STR models fit into.
Using this framework allows for the module-wise contributions to performance in terms of accuracy, speed, and memory demand, under one consistent set of training and evaluation datasets.
Such analyses clean up the hindrance on the current comparisons to understand the performance gain of the existing modules.

Honors

Based on this framework, we recorded the 1st place of ICDAR2013 focused scene text, ICDAR2019 ArT and 3rd place of ICDAR2017 COCO-Text, ICDAR2019 ReCTS (task1).
The difference between our paper and ICDAR challenge is summarized here.

Updates

Aug 3, 2020: added guideline to use Baidu warpctc which reproduces CTC results of our paper.
Dec 27, 2019: added FLOPS in our paper, and minor updates such as log_dataset.txt and ICDAR2019-NormalizedED.
Oct 22, 2019: added confidence score, and arranged the output form of training logs.
Jul 31, 2019: The paper is accepted at International Conference on Computer Vision (ICCV), Seoul 2019, as an oral talk.
Jul 25, 2019: The code for floating-point 16 calculation, check @YacobBY's pull request
Jul 16, 2019: added ST_spe.zip dataset, word images contain special characters in SynthText (ST) dataset, see this issue
Jun 24, 2019: added gt.txt of failure cases that contains path and label of each image, see image_release_190624.zip
May 17, 2019: uploaded resources in Baidu Netdisk also, added Run demo. (check @sharavsambuu's colab demo also)
May 9, 2019: PyTorch version updated from 1.0.1 to 1.1.0, use torch.nn.CTCLoss instead of torch-baidu-ctc, and various minor updated.

    pretrained-model loading with errors

    Hello, I used single GPU env with python == 3.8, torch==1.8.1 and torchvision==0.9.1 I followed the github hint with the following command:

    python3 infer.py --gpu --image demo_image/demo_2.jpg --model vitstr_small_patch16_224.pth

    It returned an error with

    AttributeError: 'collections.OrderedDict' object has no attribute 'to'

    it seems that the function model = torch.load(checkpoint) in infer.py returns an ordered dict instead of the model object. One way to solve the problem is:

    ordered_dict = torch.load(checkpoint)
model.load(ordered_dict )

    But I do not know the hyper params of vitstr_small_patch16_224.pth when it is training. so it is very hard form me to initialize the model object with correct hyper params. I would like to ask would it possible to may the hyper params of the pretrained models public?

    I also tried the pt models

    python3 infer.py --gpu --image demo_image/demo_2.jpg --model vitstr_small_patch16_jit.pt

    it gives the following error:

    About the difference between the number of training iters in the paper and this Repo

    Thanks for your great work and source code ! The training epoch numbers in the paper Table 2 are 300, but there are 300000 iters in source code . Data augmentations in the code are very thorough, I think a longer training process is necessary. Which one is your experimental strategy? I do not know if you have done similar experiments that how many iters of training performance will be basically stable under your strong data augment setting. I look forward to your reply！

    Hi, thank you for your work. This is a very meaningful job. I am curious if the input size is the same as TRBA (32 x 100). Have you tried training with 32 x 100 input-sized images?

    Question about [GO] and [s]

    Hi, thanks for your amazing work. When you convert the label using class TokenLabelConverter, you pad the label with [GO] which is ignored during loss calculation, however in paper, figure 4 shows that the label is padded with [s]. Does this make any difference on accuracy?

  • Poor performance on some images

    Poor performance on some images

    Thank you for the awesome research!

    I ran the code for demo images and it worked perfectly. But when I run the code on few sample images, the model seems to be incoherent.

    It would be great if you answer few of my questions,

    1. Does the model perform end-to-end STR or does the model require a cropped image (using for ex: EAST or TextFuseNet text detectors)? Example: 1st and 2nd images below (where 1st image is cropped version of 2nd image), same case with 5th and 6th image
    2. Does the model perform multi line text recognition?
    3. Why You Should Try the Real Data for the Scene Text Recognition paper mentions in section 4.7 a scope of improvement using OpenImage v5 dataset on this research, have you tried this?

    Examples:

    I used vitstr_base_patch16_224_aug.pth model for prediction.

    | Image | Prediction | | ----------- | ----------- | | test6 | middleborough | | test6_1 | midleerooogg | | test4 | qatm | | img_11 | aoe | | test2 | castlecampbell | | test1 | coaeeea |

    Hello @roatienza!

    Thanks for this great repo!

    I am trying to train using rand_aug but I am facing some issues. I get an error on blur.py when trying to convert from BGR to Grayscale. It seems the image has just one channel.

    `error: Caught error in DataLoader worker process 0.
