.NET

Hello every one,

We are working on a software that uses OPENOCR engine to do some OCR on given images, given we are using .NET framework , i was wondering if anyone knows about any good possible filters or sharpening methods that can be applied to the image prior to sending it to OCR engine.

I have found for example a grayscaled image is much easier for OCR engine to read than a color images.

are there any other techniques or image filttering that you guys know of , that can decrease the error margin by OCR engine ?

Thanks a million
