This page contains the materials presented in the paper
[A Two-Step Method for Ensuring Printed Document Integrity using Crossing Number Distances](https:/hal/paper.pdf).
You can find here the [impementation](#code) of proposed method in Python 3 and the augmented PaySlip [dataset](#dataset).
# Method
The implementation of our method was done using Python and standard image processing libraries, such as OpenCV, matplotlib, and scikit-image.
# Dataset
The augmented PaySlip dataset can be downloaded [here](https://gitlab.liris.cnrs.fr/gdr_isis_fuzzydoc/fuzzydoc_paper1/-/tree/master/subset). We provide 100 document images printed and scanned using X priner/scanner at 600dpi resolution.
For our dataset, we have obtained the following results :
Resolution| Genuine | Forged
:---: | :---: | :----:
PS 300dpi | 100% | 95%
PS 600dpi | 100% | 90%
Double PS 600dpi | 50% | 100%
Total mean | 83% | 95%
