For my undergrad thesis, I am required to use Shapeworks. I am new to this field and as a result, it's becoming hard for me to find out where to start. I have already gone through the documentation several times but could not find any clue regarding the algorithms Shapeworks is using. I have also read the papers titled  "Uncertain-DeepSSM: From Images to Probabilistic Shape Models" and "DeepSSM: A Deep Learning Framework for Statistical Shape Modeling from Raw Images"  but could not understand the algorithms properly. It would be really nice if you can give me some guidelines.

Thank you.
