Oracle headroom without signal: null-calibrated evaluation of candidate selection for thermal heart rate estimation
arXiv:2610.02561v1 Announce Type: new Abstract: Camera-based physiological monitoring can produce multiple estimates from several facial regions, extraction methods, and processing settings. Signal quality indices aim to select reliable estimates without a physiological reference, and their potenti…
