This paper presents a novel framework based on the non-subsampled contourlet transform (NSCT) and sparse representation (SR) to fuse the multi-focus images. In the proposed fusion method. each source image is first decomposed with NSCT to obtain one low-pass sub-image and a number of high-pass sub-images.
