Inpainting DTM and Roughness restitution

Matlab script to carry out heat diffusion based inpainting over missing data area and to render back on top of the interpolation a realistic surface roughnes/testure Credits to John D'Errico for the inpaint_nans function (https://www.mathworks.com/matlabcentral/fileexchange/4551-inpaint-nans) and to Wolfgang Schwanghart for the amazing Topo-Toolbox set of tools (https://www.mathworks.com/matlabcentral/fileexchange/50124-topotoolbox) (here I'm using rasterread and rasterwrite functions)

Usage example: download the release compressed file or clone the repository: https://github.com/HydrogeomorphologyTools/DTM-Inpainting-surface-roughness-restitution
Then run the main script (Inpaint_DTM_roughness_restitution.m) "as is" with the provided inputs and dependance files.

Feel free to test and vary parameterization, investigation is still needed on DTM-related performance.

The zip file contains all the files within the master repo.

Enjoy!
