A Hybrid Wavelet-Based Method for the Peak Detection of Photoplethysmography Signals

Figure 5

The detection error produced of subject (1) whilst under gently walking posture. (a) The FP produced using the raw data for the 2nd time, (b) the FN produced using the raw data for the 3rd time, (c) the FN produced using the raw data for the 4th time, (d) the FP produced using the corrected data for the 2nd time, (e) no error using the corrected data for the 3rd time, and (f) no error using the corrected data for the 4th time.
