Image processing applications in various field gain more and more day by day. Image enhancement is highly essential in many image processing techniques and applications. It has many applications in areas like communication engineering, medical image processing, RADAR image processing, and social security. In this paper, we have studied different spatial domain techniques for enhancement of image, both direct and indirect. For removing of noise and artifacts from the image, we have found the median filter is one of the best methods for enhancement. In first phase it has been designed and verified using MATLAB simulation. Next to it FPGA implementation is performed using VHDL and tested in SPARTAN - 3 hardware circuit board.
