Everywhere-in-focus images are more desirable for human perception and computer based analysis such as vision based industrial inspection and quality control in manufacturing. In this paper, a region based fuzzy method that combines the sharper regions of images with diverse focuses is proposed. First, source images are decomposed into image blocks. Next, a fuzzy criterion is employed to measure the sharpness of each block. Then, the sharper image block is transferred to the fused image. The proposed method is compared with the region based pixel level method. Experimental results demonstrate that the proposed image fusion method is better in both quantitative and subjective evaluations.
