DocTr is introducing distortions. Am I doing anything wrong?

[pavanbvns]

Hello there,

I am using DocTr to enhance quality of few images in my project and I am finding that DocTr is introducing distortions in the file output. Pls let me know if I am using it incorrectly.

Steps I followed.

1. Cloned the DocTr project to my google drive.
2. Copied the 3 .pth files and the image to desired location.
3. Ran the following command in the colab.
   %cd /content/drive/MyDrive/MSProject/DocTr-cloned-repo/DocTr/
   ! python inference.py --ill_rec True --distorrted_path '/content/drive/MyDrive/MSProject/temp/' --isave_path '/content/drive/MyDrive/MSProject/DocTr_output_images/'

The original file that has been used is this

The image output from DocTr is this

Comparison for ease of reference

Please let me know if this is a desired behavior or am I doing anything wrong

Request your immediate response, as I have to conclude my research and submit my project as a part of my MS program.

Thank you in advance

Hi， I am sorry for the late reply.
For our DocTr, we aim to cope with the document images captured by smartphones.
In your case, the input image seems to have been binarized, different from the data distribution used in our training.
I hope this helps!
