Abstract:

Image fusion method based on self-adaption region variance is discussed in this paper.Regional variance range is determined according to the specific image adaptively.Regional variance fusion is adopted as the image fusion method.Contourlet Transform is adopted in image transformation.Experimental result shows that our method can improve the information entropy and average gradient of the image.Compared with traditional direct fusion methods,our method can both improve the detail of the image and perform image fusion.

Key words: image fusion;regional variance fusion;detail information
