Multi-focus image fusion based on Laplacian pyramid

Packages used: numpy, skimage, scipy, matplotlib.
The algorithm follows the steps:
• Decompose two input images into Laplacian pyramids.
• Generate the top level of fused pyramid by maximum region information rule.
• Generate other levels by maximum region energy rule.
• Reconstruct fused image by performing inverse transformation to fused Laplacian pyramid.
