Framework

Dictionary learning

Reconstructure

1 made_images and made_images_new are the source images which contain different focus region.

2 image_vector and image_vector_new are the image patches matrices and each column is an imape patch which divided by sliding window technique.

3 dictionary and dictionary_new are the su-dictionaries from image_vector and image_vector_new.

1 Hog.m---extract the HOG features of image patch.

2 The code of 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

3 getClassLabel.m ---- set class label for each patch.

4 fusion_dllrr.m ---- main file.

5 The tool boxes of KSVD and OMP

The 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.
