Example of inadequate surface coverage on the ear Poor ear coverage may occur due to the angle at which the participant was facing relative to the cameras at the time of image capture (A and B), or due to interference from scalp hair (C and D). Due to the intricacy of the external ear, detailed data beyond height and width may not be attainable for some individuals (E and F).
