You should try first with synthetic image : write "Show the following Claims" using a small font and use png format to save your image. Don't use jpg format

To ask a better formatted question in the future, please format the code and output as preformatted text (the icon is the 0 1 0 1 0 1 one). I've just done this for you. This is done with three spaces at beginning of line. Thanks for actually including code as text rather than a screenshot!

Upper image is "my image" (zoom x4) : it's a color image. lower image is image in gray (cvtColor) : I don't know how to extract character in your image.

@LBerger,my upper image is sipping from existing windows forms ,but my second image is created synthetic image .That's why different background colours.

@LBerger,Removing background colour and extracting only text is also more helpfull to me.
