A new fusion scheme for multi-focus images based on dynamic salient weights on discriminative edge points

In this paper, we propose a new fusion scheme for multi-focus images based on special edge information called discriminative edge points. A new focus measure is also proposed to identify which pixels in the source images can be included in the resultant image to achieve the best fusion result by evaluating the salient weights for the discriminative edge points within a dynamic focus-measuring window whose center is the location of the pixel under current consideration. Experimental results show that our fusion scheme outperforms other seven methods reported in the literature.
