About OCR generation

[LC-John]

Hi, guys!
I am trying to reuse the OCR transformation module in TextFlint, but I somehow find it rather trivial...
I quote the code about the OCR rules in the source code as below:

mapping = {
            '0': ['8', '9', 'o', 'O', 'D'],
            '1': ['4', '7', 'l', 'I'],
            '2': ['z', 'Z'],
            '5': ['8'],
            '6': ['b'],
            '8': ['s', 'S', '@', '&'],
            '9': ['g'],
            'o': ['u'],
            'r': ['k'],
            'C': ['G'],
            'O': ['D', 'U'],
            'E': ['B']
        }

Here, the rules do not even cover the alphabet... And there are for sure more rules, eg., "w" => "vv". "m" => "rn".
I have found a dataset here (https://github.com/jie-mei/MiBio-OCR-dataset), which contains some OCR errors retrieved from real-world.
Although I find it quite annoying to parse the files in the aforementioned dataset... I believe that it may be benefitial to this work!

Hi,

Thanks for the suggestion!
We will update the function soon!

Hey @BeyonderXX is anyone working on this right now? I'm interested to have a look at this if that works

As a starter I feel just parsing and making a dictionary using this file and adding it to the current mapping if that seems fine?
