The workflow consists in two steps: the recognition of damaged areas in manuscripts and the inpainting restoration.

• 1st step: run Matlab file for segmentation combining active contour + kmeans

./manuscript_segmentation.m

• 2nd step: run bash script for the inpaint the damaged areas detected in step 1

./manuscript_inpainting.sh

The experiment with number XXX is stored in the folder “./results/paper_results/testXXX” folder, where

- 101,102,... refers to images from Manuscript 1;
- 201,202,... refers to images from Manuscript 2.

In folder ./results/paper_resultS/test101 we store the results of experiment 01 for Manuscript 1:

• input_orig101.png: the real crop of Manuscript 1;
• input101.png: the preprocessing (smoothing/texture removal);
• overlap_SUPER101.png: overlap between image crop and supervised pixel inputs in blue squares (just one pixel, dilated for display purposes);
• overlap_SUPERwithCV101.png: overlap between active contour regions in yellow and supervised pixel inputs in blue squares (just one pixel, dilated for display purposes);
• overlap_CV101png: overlap between image crop and active contour regions in yellow;
• overlap101.png: final overlap between image and segmentation from kmeans+activecontour
• mask101.png: final segmentation mask
• masked101.png: input for TV inpainting
• TVinpainted101.png: TV inpainting result
• PATCHinpainted101_PxP: results of nonlocal exemplar-based inpainting result with patch of size P and TV inpainting as initialization
