Abstract
Methods for enhancing the image of a subject, such as a patient, in a video non-contact monitoring system to provide an enhanced image with clear distinction of the subject from the background. The methods include applying a histogram equalization transform, such as a contrast limited adaptive histogram equalization (CLAHE) transform, to the depth data obtained from a camera of the monitoring system. In some embodiments, the enhanced image of the subject is merged with an overlay image of a monitored physiological parameter determined by the non-contact patient monitoring system.
