Praveen vanaparthy, Sahitya.G, Krishna Sree and Dr.C.D.Naidu

Digital image enhancement techniques are to improving the visual quality of images. Main objective of image enhancement is to process an image so that result is more suitable than original image for specific application. This paper presents real time hardware image enhancement techniques using field programmable gate array (FPGA). This paper focus on implementation of image enhancement algorithms like brightness control, contrast stretching, negative transformation, thresholding, filtering techniques on Fpga that have become a competitive alternative for high performance digital signal processing applications. These algorithms successfully implemented on retinal images in Verilog HDL using Xilinx ISE, MATLAB and MODELSIM. The aim of this paper is to simulate and implement these algorithms using verilog HDL. The device selected here for implementation is (Spartan-3E) from Xilinx.
