Fusion Scheme for fusing images with diverse focuses using index of fuzziness as a focus measure

Multi-focus image fusion combines relevant information from several images into a single image to provide maximum information content from the source images with different focal settings. These images are obtained from the sensors which cannot be able to generate an image with all the objects in focus. The information level or content in the multi-focus images has been measured using the focus measures and it is employed in the fusion of images with diverse focuses. A novel method to fuse images using Index of Fuzziness as a focus measure is proposed in this paper and it is compared with the existing focus measures like sum modified laplacian, spatial frequency, Variance and energy of image gradient. The performance analysis for the fusion process is carried out by means of a reference metric and a non-reference metric and it outperforms the other spatial domain methods
