Facial feature selection for heart rate detection

A computing device, comprising:

• a processor;
• a first camera having a first field of view;
• a second camera separated by a distance from the first camera, the second camera having a second field of view that at least partially overlaps the first field of view;
• and
• memory device including instructions that, when executed by the processor, cause the computing device to:
• capture first image data using the first camera and second image data using the second camera, the first image data and the second image data being captured concurrently;
• analyze the first image data to determine a first representation of a face corresponding to a user of the computing device;
• analyze the second image data to determine a second representation of the face;
• analyze the first representation of the face using a first facial feature recognition algorithm;
• determine an eye location in the first representation of the face, the eye location associated with a first set of pixel values included in the first representation of the face;
• analyze the first representation of the face to identify a heart rate detection portion of the first representation of the face;
• determine a heart rate detection location of the heart rate detection portion, the heart rate detection location associated with a second set of pixel values included in the first representation of the face;
• and
• determine a first offset between the eye location and the heart rate detection location, the first offset comprising a number of pixels between the eye location and the heart rate detection location in the first representation of the face.
