ABSTRACT
Multifocus image fusion is the process of combining several images from the same scene
with different focused object into an image with better focus across all area. The blurred part
of multifocus images is a low-pass filtering process and Gaussian filter is often used in this
process. Mutlifocus image can be fused using Laplacian Pyramid (LP). LP is computed
using two basic operation: reduce and expand that involve low-pas filter. The filter used in
LP is Gaussian. In this paper, we propose a multifocus image fusion using LP based on a
class of Alpha Stable filters. We apply this method to two cases multifocus imges: (i)
multifocus images where the blurred part is generated using Gaussian filter and (ii)
multifocus images with blurred part is from Alpha Stable filter and non-Gaussian. And the
proposed method give the better results on both cases.
