Standard Cheque MICR Code Recognition using OCR

[britnis]

Hi Loïc,

I am using GdPicture version 5.12.8 for developing an application that performs OCR on scanned Image documents such as different forms or cheques. But, I have found that even with higher resolution images of cheques the OCR module is not able to recognize the Cheque MICR codes at all.

Kindly let me know whether MICR codes recognition is supported by the GdPicture or not and if it is then is there any specific way to do the same. Waiting for your reply.

Thanks and Regards

Hi,

Usually MICR reading code requires a dedicated toolkit. The tesseract plugin has not been designed for such task.
However, I know that some customers has been able to read MICR data from bank checks but they had to apply image processing first (I don't remember which). If you attach an image with undesired result we will be able to investigate.

With best regards,

Hi Loïc,

I am attaching a demo Cheque for you to verify the OCR functionality with the MICR Code and for further investigation. Please let us know as soon as possible.

Thanks and Regards

Hi,

Here some suggestion to increase OCR accuracy:

- Increase image resolution. IE: 200 or 300 DPI. Your image is scanned in 100 DPI and it is really to low.
- You can threshold the image with hih thresholding value. IE: oGdPictureImaging.FxBlackNWhiteT(ImageID, 170)
- You can try to dilate characters using the FxDilate filter.

Hope this helps,

Loïc
