Synopsis  : 

In this paper, an image fusion technique in spatial domain using an image variance as a focus measure has been demonstrated and discussed. The image variance (IV) is used as a focus measure to measure the depth of field in the images. Then it is applied in the fusion process of fusing images in diverse focuses. The experiments were performed on a set of left and right focused images and the fused results were evaluated with various equal sub block sizes of the images.
