I'm trying to automate a process where someone manually converts a code to a digital one.
Then I started reading about OCR. So I installed tesseract OCR and tried it on some images. It doesn't even detect something close to the code.
I figured after reading some questions on stackoverflow, that the images need some preprocessing like skewing the image to a horizontal one, which can been done by openCV for example.
Now my questions are:
- What kind of preprocessing or other methods should be used in a case like the above image?
- Secondly, can I rely on the output? Will it always work in cases like the above image?
I hope someone can help me!
