Multi-focus Image Fusion Based on Automatic Focus Algorithm
基于自动聚焦算法的多聚焦图像融合*

The paper proposes a multi-focus image fusion algorithm based on the amended automatic focus algorithm. Its main idea: first, the registered source images are divided into a lot of blocks, then using the DCT matrix of each block and the neighboring coherence in space locates the area of focus; the blocks in the focuses will be transplanted into the fused image, and the middle of area in two images between focuses will be fused by selective maximum rule. Experiments show, the fused image based on blocked DCT is the most approximation to the source images, and more than the fused result based on the WT fusion rule.
