Image Fusion Technique Implementation Using FPGA

Abstract

In recent times, the application of Image fusion have grown immensely in the areas of medical science, forensic and defense departments. An image fusion technique is used to create a fused image that gives all the useful information from the source image. Image fusion process is nothing but the integration of information from a number of registered input images without the distortion. Image fusion produces a single image by fusing information from a group of input source images together using either pixel, feature or decision level techniques. The fused image contains better information content for the scene than any one of the individual input images alone. The accuracy and overall detailed information of the image is increased. This system deals with the design of image fusion technique in MATLAB using Discrete Wavelet Transform (DWT) technique. The system is then interfaced on FPGA with the help of Xilinx.
