A new research paper introduces PUMA, a novel method for forensic image manipulation localization. PUMA addresses limitations in existing methods by explicitly preserving quality-mismatch information and adaptively selecting the order of information propagation. The approach combines spatially constrained unbalanced optimal transport with position-wise convex selection, retaining signed transport-mass residuals and updating noise features through a gated residual path. Experiments show PUMA achieves strong localization results, outperforming representative methods on COVERAGE and NIST16 datasets. AI
