Implementation of image fusion based on wavelet domain using FPGA

Image fusion is a data fusion technology which keeps images as main research contents. It refers to the techniques that integrate multi-images of the same scene from multiple image sensor data or integrate multi images of the same scene at different times from one image sensor. 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 10.1 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. Finally, the proposed algorithm in this project was applied to experiments of multi-focus image fusion and complementary image fusion. The algorithm will be transferred from computer to FPGA board using JTAG cable. The result will be transferred back to system to analyze hardware resource taken by FPGA using Visual Basic.
