This work focuses on recovering the blurry text image.
Based on the deep neural network, a new short connection scheme is used. Trained by the pixel regression, higher visual quality of the image can be recovered by the network from the blurry one.

Check the matlab script 'Matlab/RunProcess.m': The path of the text images should contain raw sharp text images. You can build your own dataset by convert PDF files into raw image files and save them to the text image path in "Matlab/RunProcess.m".
Then run the matlab script 'Matlab/RunProcess.m', which helps to build the training dataset.
-
Check the training data and model saving paths in "train.py", for which the training data should be consistent with the previous step. Then run the following script:
python train.py
-
Check the testing model and data paths in "test.py". Then run the following script:
python test.py
