Batch Processing with HED without MATLAB

[AndroXD]

I'm following the "Batch Processing" procedure here ( https://github.com/s9xie/hed#batch-processing ) and got to the point where I run "batch_hed.py" ( https://github.com/phillipi/pix2pix/blob/master/scripts/edges/batch_hed.py ) and all my pictures are converted into .MAT files (MATLAB) files, the final step requires to run "PostprocessHED.m" ( https://github.com/phillipi/pix2pix/blob/master/scripts/edges/PostprocessHED.m ) to convert them into normal pictures, but instructions says that I need MATLAB to do it: "get the cpp file edgesNmsMex.cpp from https://raw.githubusercontent.com/pdollar/edges/master/private/edgesNmsMex.cpp and compile it in Matlab: mex edgesNmsMex.cpp You also need to download and install Piotr's Computer Vision Matlab Toolbox: https://pdollar.github.io/toolbox/" Is there any method to do it for free without MATLAB? That's a proprietary paid software. I noticed that the author of this Google Coolaboratory is using Octave as a free alternative to MATLAB: https://colab.research.google.com/drive/1SI57hLgHCX6mbZ2jNveNvq1Pqx07Jag7 , so I guess a 100% free approach is definitely possible, however, that Coolaboratory works only online, I'd like a local/offline solution for Windows 10 like I'm doing now if possible. Any help is much appreciated, thank you very much for your kind attention!
