Wavelet-Based Digital Image Fusion on Reconfigurable FPGA Using Handel-C Language

Field Programmable Gate Array (FPGA) technology has become a viable target for the implementation of real time algorithms in different fusion methods have been proposed mainly in the fields of remote sensing and computer vision. Image fusion is basically a process where multiple images (more than one) are combined to form a single resultant fused image. This fused image is more productive as compared to its original input images. In most paper image fusion algorithms were implemented in simulation level only. In this paper Wavelet based Image fusion algorithm is employed and implemented on a Field-Programmable-Gate-Array-based hardware system using a Xilinx Platform Studio EDK 11.1 FPGA Spartan 3E is implemented. The FPGA technologies offer basic digital blocks with flexible interconnections to achieve high speed digital hardware realization. The FPGA consists of a system of logic blocks, such as Look up Tables, gates, or flip-flops and some amount of memory. The algorithm will be transferred from computer to FPGA board using JTAG cable. In this proposed work algorithm is developed by using Handle –C language to performing wavelet based image fusion. The result will be transferred back to system to analyze hardware resource taken by FPGA.
