1. A method comprising:
acquiring an image of a user;
recognizing a region of interest (ROI) in the image, wherein the ROI is an area of skin on the user's face that is perfused with blood;
analyzing the ROI to generate statistics, wherein the statistics include heart rate variability (HRV), wherein analyzing the ROI involves decomposing the ROI data into a plurality of color channels and applying one or more spatial filters to the color channels;
determining a level of stress experienced by the user based on the statistics;
providing one or more interventions to the user to reduce the level of stress, wherein interventions provided to the user are filtered based on effectiveness ratings provided by the user;
prompting a user to rate effectiveness of each of the one or more interventions; and
maintaining a mitigation database that is updated with user effectiveness ratings for each of the one or more interventions.
