Laplacian Pyramid (LAP) based image fusion has been implemented in FPGA. A concept of weighted laplacian energy based fusion has been applied. Eighty percent of pixel weight from high Laplacian energy and twenty percent pixel weight from low Laplacian energy gives better results than traditional high Laplacian energy based fusion algorithm. Entropy as a measure of quality of fused image has been considered. This approach is simulated in PC environment using MATLAB and has also been implemented in Xilinx’s Virtex 5 SX FPGA.
