Is removing the Matlab dependency possible? about deep-photo-styletransfer HOT 8 CLOSED

For Clarity on @luke14free comment:
On the command line:

cd [parent directory of deep-photo-styletransfer]
sudo apt-get install liboctave-dev
wget https://downloads.sourceforge.net/project/octave/Octave%20Forge%20Packages/Individual%20Package%20Releases/image-2.6.1.tar.gz?r=&ts=1491430627&use_mirror=superb-sea2
mv image-2.6.1.tar.gz?r= image-2.6.1.tar.gz

Then run inside of octave, by launching octave on the command line:
octave

pkg install image-2.6.1.tar.gz
pkg load image
run('deep-photo-styletransfer/gen_laplacian/gen_laplacian.m')

from deep-photo-styletransfer.

first run
$ sudo apt-get install liboctave-dev
then from octave after you downloaded image-2.6.1.tar.gz from https://octave.sourceforge.io/image/ run pkg install image-2.6.1.tar.gz, finally run pkg load imageand then execute the script. Note that then I had an issue with some directories not being correctly imported (and there was an undefined getLaplacian1()), to fix it simply change the first two lines of the matlab file to:

addpath matting/
addpath gaimc/

(basically reversing the slash)

@luanfujun Is using Octave: https://www.gnu.org/software/octave/ instead of Matlab possible without modifying the code? Octave appears to support all the required Matlab stuff, and it's free and open source software.

Edit: Testing Octave:

ubuntu@ip-Address:~/deep-photo-styletransfer$ octave

octave:1> run('gen_laplacian/gen_laplacian.m')
warning: addpath: matting\: No such file or directory
warning: addpath: gaimc\: No such file or directory

Ah... Yes it is possible. The only Matlab part in this project is to compute the matting Laplacian matrix, Eq. 12 in this paper with their Matlab code. Similar issue to #1.

@luke14free I got Octave to work by doing the same things that you described, but the .Mat files it creates don't work in the deepmatting script for me. Do they work for you?

Is there a solution for this running on Mac instead of Ubuntu? I'm running into the same 'im2double' undefined problem trying to run run('gen_laplacian/gen_laplacian.m') in Octave :(

I removed the MATLAB/Octave dependency in my fork: https://github.com/martinbenson/deep-photo-styletransfer

@martinbenson Thanks! This is perfect
