Study Text Image Resolution Using Soble Operator

Abstract

Color imaging effective field for since research it is continue development as a result of fast development that happened in computer world. The studies text image is apart of this development .In this research we are imaging three text which are writing in Arabic language on white background by digital camera in good lightness.
