When human bodies overlap in crowds, the algorithms we trust to read posture and position begin to lose their footing — mistaking one person's limb for another's, losing joints behind torsos. A team of researchers has answered this perennial failure of machine perception with PSEG, a framework that teaches systems to trace the outline of a human form even when that form is partially hidden, offering modest but consistent improvements across the benchmarks that matter most. The work is less a revolution than a careful repair — a quiet insistence that the tools we build for seeing people should
