This is the opensourced OCR repository of DAVAR Lab, from Hikvision Research Institute, China.
We begin to maintain this code repository to release the implementations of our recent academic publishments and some re-implementations of previous popular algorithms/modules in OCR.
We also provide some of the ablation experiment comparasions for better reproduction.
Note: Due to the policy limits of the company. All of the codes were re-implemented based on the open-source frameworks, mmdetection-2.11.0 and mmcv-1.3.4, from open-mmlab. The code architecture also refers to mmocr, which means these two frameworks can be well compatible to each other.
To date, davarocr contains the following algorithms:
- TRIE (ACM MM 2020)
Video Text Spotting
YORO (ACM MM 2019)
FREE (to be released) (TIP 2021)
- LGPMA (ICDAR 2021)
- VSR (ICDAR 2021)
The recommended environment requirements can be found in mmdetection. Follows are the lowest compatible environment.
For some of the algorithms (EAST, Text Perceptron), C++ version opencv are required. If you do not need to use these algorithms, you could temporarily ignore the error about 'opencv.hpp' or remove the related codes temporarily.
Installation and Development Instruction
To Download the repository and install the davarocr, please follow the instructions:
git clone https://github.com/hikopensource/DAVAR-Lab-OCR.git cd DAVAR-Lab-OCR/ bash setup.sh
This script will automatically download and install the "mmdetection" and "mmcv-full". You can also manually install them followinging the official instructions
Going to the specific algorithm's directory to see more details.
Problem solution and collection
For the problems existing in the process of installation and researching, we will reasonably collect them and provide corresponding solutions. Please refer to FAQ.md for details.
DavarOCR v0.4.0 was released in 12/31/2021. Please refer to Changelog.md for details and release history.
