The following error is produced when multiple people are looking at the camera which is then recovered when there is only one person.

Issue re-appears occasionally but not as frequently as before. Will likely require a fix to drop the frame from calculation if bounding boxes are outside of the image (i.e. face is on edge of image leading to the eye patch extending the buffer outside of the image boundry)
