Unsupervised 3D reconstruction of small rocks from a single 2D image
… “Unsupervised”???
“Unsupervised” often refers to a type of machine learning. With “supervised” machine learning you get a training data set that has the correct answers attached– so the program can check (or supervise) its own accuracy.
In my experience, unsupervised algorithms are often used for clustering (grouping items into categories which are not predefined). I have no fucking idea how an unsupervised algorithm gets this fucking good at this.
…. but there is a link to a research paper about how they made this and now I have to read it because I’m curious.
Basically the researchers preprogrammed a lot of assumptions about the shapes of pebbles, and this isnt very generalizable.
This likely wouldnt even work for a picture which had some scattered pebbles on a flat surface with the flat surface visible, but I’m super super curious how this algorithm would interpret pictures like that as well as non-pebble pictures in general.
