Motion artifact detection and reduction in PPG signals based on statistics analysis

The performance of pulse oximeters is highly influenced by motion artifacts (MA) in photoplethysmographic (PPG) signals. MA can't be eliminated completely by using the traditional filtering algorithms, which results in the error in the measurement of blood oxygen, so this paper presents a new method to detect and remove MA in PPG signals. The statistics of the segmented signals are detected by setting a threshold and high-quality signal segments...
