Multi-Focus Image Fusion via Clustering PCA Based Joint Dictionary Learning
This paper presents a novel framework based on the non-subsampled contourlet transform (NSCT) gruvi golden lager 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.Second, an SR-based scheme
