Dear All,
I am now needing to OCR the embossing characters on the bank card.
These characters are in two kind of font. The first one is Farrington 7B,
which is used to present the account number, and another font is
unknown(maybe bank-dependent) and is used to present card holder name, card
issue time and card serial number.
Now the problem is the embossing characters are very difficult to OCR
since they will be very bright under special light. While if the extra
light is not applied, the card background will largely affect these
characters, and will cause error.
I have uploaded two images. The first sample image shows that improper
light applied will cause the characters to be dark/light mixed and OCR
result is very bad. The second image shows that a better light will make
the background dark and embossing characters very sharp, while the OCR
result is a little bit better, but still not good enough.
Can anybody give me some advice on the light applied, or image
pre-processing technique to improve the OCR result? Thank you all!
