Guided filter-based multi-focus image fusion through focus region detection

作者：

Highlights：

• A focus region detection method based on guided filter and mean filter is proposed.

• The detection method has well clarity evaluation and strong robustness to noise.

• A multi-focus image fusion method based on the detection method is proposed.

• Our method performs well in grayscale or color image and implements efficiently.
