Detecting Text in Natural Image with Connectionist Text Proposal Network
The codes are used for implementing CTPN for scene text detection, described in:
Z. Tian, W. Huang, T. He, P. He and Y. Qiao: Detecting Text in Natural Image with Connectionist Text Proposal Network, ECCV, 2016.
Online demo is available at: textdet.com
These demo codes (with our trained model) are for text-line detection (without side-refinement part).
You need a GPU. If you use CUDNN, about 1.5GB free memory is required. If you don't use CUDNN, you will need about 5GB free memory, and the testing time will slightly increase. Therefore, we strongly recommend to use CUDNN.
It's also possible to run the program on CPU only, but it's extremely slow due to the non-optimal CPU implementation.
Python2.7, cython and all what Caffe depends on.
How to run this code
Clone this repository with
git clone https://github.com/tianzhi0549/CTPN.git. It will checkout the codes of CTPN and Caffe we ship.
Install the caffe we ship with codes bellow.
Install caffe's dependencies. You can follow this tutorial. Note: we need Python support. The CUDA version we need is 7.0.
Enter the directory
cp Makefile.config.example Makefile.config.
Open Makefile.config and set
WITH_PYTHON_LAYER := 1. If you want to use CUDNN, please also set
CUDNN := 1. Uncomment the
CPU_ONLY :=1if you want to compile it without GPU.
Note: To use CUDNN, you need to download CUDNN from NVIDIA's official website, and install it in advance. The CUDNN version we use is 3.0.
make -j && make pycaffe.
After Caffe is set up, you need to download a trained model (about 78M) from Google Drive or our website, and then populate it into directory
models. The model's name should be
Now, be sure you are in the root directory of the codes. Run
maketo compile some cython files.
python tools/demo.pyfor a demo. Or
python tools/demo.py --no-gputo run it under CPU mode.
How to use other Caffe
If you may want to use other Caffe instead of the one we ship for some reasons, you need to migrate the following layers into the Caffe.
