OpenGL Deprecated - is it required for this process?

This is a really cool implementation! Works great with clean masked areas.
Is there a specific reason OpenGL/GPUImage is used as it is deprecated?
Thanks

Update: As a test, I was able to completely remove the GPUImage/OpenGL dependency by removing the edge detect step.
It works by using the inpainting model and completely skipping the edge detect step which is what is using GPUImage/OpenGL.
I haven't tested or compared the quality of inpainting.
