MMOCR is an open-source toolbox based on PyTorch and mmdetection for text detection, text recognition, and the corresponding downstream tasks including key information extraction. It is part of the OpenMMLab project.
The main branch works with PyTorch 1.6+.
Comprehensive Pipeline
The toolbox supports not only text detection and text recognition, but also their downstream tasks such as key information extraction.
Multiple Models
The toolbox supports a wide variety of state-of-the-art models for text detection, text recognition and key information extraction.
Modular Design
The modular design of MMOCR enables users to define their own optimizers, data preprocessors, and model components such as backbones, necks and heads as well as losses. Please refer to Getting Started for how to construct a customized model.
Numerous Utilities
The toolbox provides a comprehensive set of utilities which can help users assess the performance of models. It includes visualizers which allow visualization of images, ground truths as well as predicted bounding boxes, and a validation tool for evaluating checkpoints during training. It also includes data converters to demonstrate how to convert your own data to the annotation files which the toolbox supports.
While the stable version (0.6.2) and the preview version (1.0.0) are being maintained concurrently now, the former version will be deprecated by the end of 2022. Therefore, we recommend users upgrade to MMOCR 1.0 to fruitful new features and better performance brought by the new architecture. Check out our maintenance plan for how we will maintain them in the future.
v0.6.2 was released in 2022-10-14.
Read Changelog for more details!
A brand new version of MMOCR v1.0.0rc2 was released in 2022-10-14:
New engines. MMOCR 1.x is based on MMEngine, which provides a general and powerful runner that allows more flexible customizations and significantly simplifies the entrypoints of high-level interfaces.
Unified interfaces. As a part of the OpenMMLab 2.0 projects, MMOCR 1.x unifies and refactors the interfaces and internal logics of train, testing, datasets, models, evaluation, and visualization. All the OpenMMLab 2.0 projects share the same design in those interfaces and logics to allow the emergence of multi-task/modality algorithms.
Cross project calling. Benefiting from the unified design, you can use the models implemented in other OpenMMLab projects, such as MMDet. We provide an example of how to use MMDetection's Mask R-CNN through MMDetWrapper
. Check our documents for more details. More wrappers will be released in the future.
Stronger visualization. We provide a series of useful tools which are mostly based on brand-new visualizers. As a result, it is more convenient for the users to explore the models and datasets now.
More documentation and tutorials. We add a bunch of documentation and tutorials to help users get started more smoothly. Read it here.
Find more new features in 1.x branch. Issues and PRs are welcome!
MMOCR depends on PyTorch, MMCV and MMDetection.
Below are quick steps for installation.
Please refer to Install Guide for more detailed instruction.
conda create -n open-mmlab python=3.8 pytorch=1.10 cudatoolkit=11.3 torchvision -c pytorch -y
conda activate open-mmlab
pip3 install openmim
mim install mmcv-full
mim install mmdet
git clone https://github.com/open-mmlab/mmocr.git
cd mmocr
pip3 install -e .
Please see Getting Started for the basic usage of MMOCR.

Please refer to model_zoo for more details.
We appreciate all contributions to improve MMOCR. Please refer to CONTRIBUTING.md for the contributing guidelines.
MMOCR is an open-source project that is contributed by researchers and engineers from various colleges and companies. We appreciate all the contributors who implement their methods or add new features, as well as users who give valuable feedbacks.
We hope the toolbox and benchmark could serve the growing research community by providing a flexible toolkit to reimplement existing methods and develop their own new OCR methods.
