Graph Neural Networks for Computer Vision

I was attracted by this image:

This is an inspiring image and it was posted in this article: Tutorial on Graph Neural Networks for Computer Vision and Beyond (Part 1) written by Boris, a PhD student at University of Guelph.

The figure I attached above is showing some possibilities that using the graph structure to represent the version components in a fuzzy way. That's innovative and interesting.
