Texte reconstruction in image

Hello everyone !

I need your help for an image reconstruction.
Indeed, for a simple image containing text I can recognize the text with Tesseract .
But If there is noise on the text, like trais, Tesseract can't read the text.

I thought I had to remove picture noise by changing the colors with the following function :

_ImageColorRegExpReplace($hImage, "(000000FF)" , "FFFFFFFF" )

But if there are trais on the texts, this one becomes as the following picture (for example) :
 img5.tif

Made the text unreadable by Tesseract .

Can you give me a track to rebuild the text?
I read this article, but it doesn't much helped me because the links are dead ...

Thanks for your help and sorry for my english if i made some faults ;)
