Dirichlet-field segmentation with uncertainty estimation

Variational and neural segmentation methods that combine Dirichlet uncertainty fields with anisotropic spatial regularization.

This project formulates image segmentation as an optimization problem in which predictive uncertainty is represented by Dirichlet concentration parameters and regularized with structure-aware spatial terms.

The work aims to improve calibration, preserve edges, and retain computational efficiency by avoiding repeated stochastic inference wherever a principled closed-form uncertainty calculation is possible.
