SpO2 miniprogram: AI SpO2 measurement app

A method performed by at least one computer processor comprising:

• controlling a camera of a mobile phone to capture a video of at least a portion of skin;
• extracting at least one photoplethysmogram (PPG) signal from the video;
• statistically processing the PPG signal and removing a portion of the PPG signal based on determining the portion to be noisy data by comparing a result of the statistical processing to at least one predetermined threshold;
• determining a peripheral oxygen saturation (SpO2) value based on the PPG signal, after the portion is removed from the PPG signal, with respect to a blood flow at the portion of skin;
• and
• controlling a display of the mobile phone to display the SpO2 value.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
