Hello,
I have a project in which I'd like to be able to extract features from stl. files of the crowns of teeth (the crown of a teeth is that what you can see when you open your mouth). I have read so many articles in which something similar is being done, but there's never the code for it to be found.
My Input so to say is a stl. file of the surface of the crown, which I want to analyse (feature extraction) to compare it with other teeth (same type of teeth but from another person). The idea is to get the features of every tooth, which should be similar (for example the width of the crown or some characteristic curves) and make a crown with the mean of these features from every tooth.
Can someone give me some advice?
Every bit of help is welcome :D
(I don't want you to do the work for me, just point me in the right direction)
Thank you.

Hi Diego,
You can use generative networks during the process of training data, you can train an autoencoder which takes images from STL file as input, does the process of feature extraction and again convert it into images which is input, you can do it for enough number of images.
Now during the inference, you can take 'n' number of people teeth, extract feature, take the mean and again convert it into images.
Hope this Helps!

Hi Diego,
Yes, For more information I recommend you to refer autoencoder which performs unsupervised learning of features using autoencoder neural networks.

Hi, I've read yours answers and I have a question. In wich way is possible to extract a set of images from an stl?
Thank you, Raffaele.
