Convex hull algorithms based on some variational models
Lingfeng Li, Shousheng Luo, Xue-Cheng Tai +1
The paper introduces two variational level‑set models for computing convex hulls of 2‑D data, one exact and one robust to outliers, and solves them efficiently with ADMM.

An ensemble Kalman filter approach based on level set parameterization for acoustic source identification using multiple frequency information
Zhiliang Deng, Xiaomei Yang
The paper proposes a statistical inversion method that combines an ensemble Kalman filter with level set parameterization to reconstruct spatially varying acoustic sources from noi…
