## Figures
1 original_images  

2 mf_noise_images  ---- multi-focus images contain different noises

3 focus_images ---- sources images


## Source code
1 main.m --- test demo.

2 'methods' - multi-scale transform frameworks

3 The code of LRR in 'lrr'

	solve_lrr.m

	solve_l1l2.m

	inexact_alm_lrr_l1l2.m, inexact_alm_lrr_l1.m

	exact_alm_lrr_l1l2.m, exact_alm_lrr_l1.m

## LRR parts
Thr LRR method is proposed by Guangcan Liu in 2010.

"Liu G, Lin Z, Yu Y. Robust Subspace Segmentation by Low-Rank Representation[C]// International Conference on Machine Learning. DBLP, 2010:663-670."

And we just use this method in our paper without change.
