Digital image enhancement methods are used to increase the photographic quality of images. The main objective of any enhancement method is obtaining a more suitable result compared with the original form. Any image enhancement techniques can be categorized into two methods: spatial domain methods and frequency domain methods. This project concentrates on image enhancement in the spatial domain, with particular reference to point processing methods like: contrast manipulation, brightness manipulation, inverting images, threshold operation. This project presents concept of hardware software co-simulation for image processing using Xilinx System Generator (XSG).This technique, provides a set of Simulink blocks (models) for several hardware operations that could be implemented on various Xilinx FPGA.
