Deep adaptative spectral zoom for improved remote heart rate estimation

2024 IEEE 18th International Conference on Automatic Face and Gesture Recognition (FG)
Recent advances in remote heart rate measurement, motivated by data-driven approaches, have notably enhanced accuracy. However, these improvements primarily focus on recovering the rPPG signal, overlooking the implicit challenges of estimating the heart rate (HR) from the derived signal. While many methods employ the Fast Fourier Transform (FFT) for HR
