Determining Oxygen Levels From Images of Skin - A simplified explanation of the abstract

This abstract first appeared for US patent application 18213461 titled 'Determining Oxygen Levels From Images of Skin

Simplified Explanation

The patent application describes a method for estimating the oxygen saturation in a person's blood using images of their skin illuminated by ambient light. The method involves analyzing the images to identify microregions in the person's skin and determining regions of interest based on the similarity between these microregions. For each region of interest, a remote photoplethysmogram (rPPG) signal is calculated using the sequence of images. Finally, the oxygen saturation in the person's blood is estimated based on the rPPG signals.

  • The method analyzes images of a person's skin illuminated by ambient light.
  • Microregions in the person's skin are identified and used to determine regions of interest.
  • A remote photoplethysmogram (rPPG) signal is calculated for each region of interest.
  • The oxygen saturation in the person's blood is estimated based on the rPPG signals.

Potential applications of this technology:

  • Non-invasive monitoring of oxygen saturation in medical settings.
  • Fitness and wellness tracking devices.
  • Sleep monitoring devices.
  • Remote health monitoring systems.

Problems solved by this technology:

  • Provides a non-invasive method for estimating oxygen saturation in the blood.
  • Eliminates the need for invasive procedures such as blood sampling.
  • Enables continuous monitoring of oxygen saturation in real-time.

Benefits of this technology:

  • Non-invasive and painless method for monitoring oxygen saturation.
  • Continuous monitoring allows for early detection of oxygen saturation abnormalities.
  • Can be integrated into wearable devices for convenient and portable monitoring.


Original Abstract Submitted

In one embodiment, a method includes accessing a sequence of images of a portion of a person's skin illuminated by ambient light and determining, from at least one of the images, a plurality of microregions in the portion of the person's skin. The method further includes determining, based on a similarity between particular microregions of the plurality of microregions, one or more regions of interest of the person's skin; determining, for each of the regions of interest, a remote photoplethysmogram (rPPG) signal based on the sequence of images; and determining, based on one or more of the rPPG signals, an estimate of an oxygen saturation in the person's blood.
