An end-to-end spatial-temporal transformer with illumination augmentation, Residual Temporal Standardization Module, and hybrid waveform-spectral loss achieves 0.79 bpm MAE and 0.982 correlation on a new varied-illumination dataset, outperforming PhysFormer by 93.6% in MAE.
rPPG algorithms with Lp-norm and fractional-order peak enhancement achieve 1.92 bpm MAE for pulse rate and good HRV metrics vs ECG in 29 drivers, recommending 2SR for rate and CHROM for variability with 20 superpixels.
