Researchers have developed a novel mesh-free auxiliary loss function for implicit neural representations, utilizing level-crossing density derived from Minkowski functionals. This method offers a significant speedup, being approximately 250 times faster than traditional persistent homology losses. While effective in 2D for repairing topology and preserving fidelity, the technique faces challenges in 3D, where gradient descent can obscure topological noise below the sampling density, impacting accuracy.
