To test if the files give the expected result please, first run the script:
demo_fhr_us.m
You should see:
Name of recording: test1 Total difference along all windows: 0.000000 bpm Score comparison: Exact match with gold standard output
Name of recording: test2 Total difference along all windows: 0.000000 bpm Score comparison: Exact match with gold standard output
There may be a small difference, but no more than a fraction of one BPM.
To estimate FHR from test signals located in ../Recording folder. run script:
estimatingFHR.m
The FHR estimation function is called: getFRH.m
