文摘
- •
A novel multi-focus image fusion algorithm is proposed based on depth extraction.
- •
Adaptive depth estimation improves the solution of inhomogeneous diffusion equation.
- •
The images are divided into three regions according to the depth map.
- •
The multi-focus images are fused with different weights in different regions.
- •
The proposed method outperforms the state-of-the-art methods in most cases.
