Image processing in C# - Normalise a captcha image.

I need someone to write some C# image processing code to make a weakly scrambled Captcha readable via OCR ([login to view URL])

This requires

1. Removal of background gradient

2. Removal of black line

3. Make text bolder

The reliability needs to be over 90%, for job completion.

I can provide an unlimited number of captcha images in this format.
