Self‐supervised non‐rigid structure from motion with improved training of Wasserstein GANs

IET Computer Vision, 2023
This study proposes a self‐supervised method to reconstruct 3D limbic structures from 2D landmarks extracted from a single view. The loss of self‐consistency can be reduced by performing a random orthogonal projection of the reconstructed 3D structure ...
