Imagemagick bold text

I have an image which contains some text in it. My OCR software recognizes it properly only if the text is in bold. I was wondering if there is any way by which i can make the text in an image bold using ImageMagick before i send it to OCR.

Any help is 开发者_开发技巧appreciated.

THanks

You can try to increase the bright or contrast:
