at least one image capture element disposed in a hospital bed and configured to generate an image parameter of a patient disposed in the hospital bed; and
at least one processor configured to generate a temperature map of the patient from the image parameter; wherein the processor is further configured to generate, from the image parameter, a segmented model of the patient, the segmented model representing a vector illustration of the patient's body, wherein the segmented model comprises a plurality of segments, and wherein the processor is further configured to:
determine a temperature parameter of at least one segment of the segmented model;
determine a midpoint of each segment of the segmented model;
determine a position and an orientation of each midpoint of each segment of the segmented model; and
generate at least one movement parameter of the patient from the analysis of the position and of the orientation of each midpoint of each segment of the segmented model generated at different time instants.
2. The system according to claim 1 , wherein the processor is configured to generate, from the image parameter, a contour of the image parameter of the patient.
