PPG signal post-processing #252

Closed xlsay closed 7 months ago

xlsay commented 7 months ago

Hi, the model output is in PPG signals. How can it be converted to corresponding heart rate values? Thanks.

I suggest taking a look at how /evaluation /post_process.py uses the function calculate_metric_per_video to calculate the HR. It should be noted that many of the deep-models output a diffed pulse signal (equal to applying np.diff to pulse signal).

Ok, thank you very much!
