1. A system for monitoring a medical care environment, the system comprising:
- an imaging device having an imaging plane, the imaging device configured to receive a plurality of depth frame images comprising a plurality of pixels, the plurality of depth frame images representing a three-dimensional environment corresponding to a physical space, the physical space including at least one of a bed or a chair;
at least one computing device in communication with the imaging device, the at least one computing device including;
a memory configured to store one or more modules;
a processor coupled to the memory, the processor configured by a fusion engine and the one or more modules to cause the processor to;
generate a depth mask representing the physical space based upon the plurality of depth frame images;
identify one or more first pixels of the plurality of pixels as representing the at least one of the bed or the chair based upon the depth mask;
identify one or more second pixels of the plurality of pixels as representing a portion of a body of a subject proximate to the at least one of the bed or the chair;
process, via a first processing technique, the one or more second pixels to generate a first possible orientation signal of the portion of the body with respect to the image plane, the first possible orientation signal representing a position of the portion of the body with respect to the at least one of the bed or the chair;
process, via a second processing technique via the fusion engine, the one or more second pixels to generate a second possible orientation signal of the portion of the body with respect to the image plane, the second possible orientation signal representing the position of the portion of the body with respect to the at least one of the bed or the chair;
determine a probability distribution based upon the first possible orientation signal and the second possible orientation signal via the fusion engine;
determine a transitional state of the subject based upon the probability distribution; and
issue an electronic communication based upon the determined transitional state of the subject, the electronic communication comprising an alert indicating the transitional state of the subject.

Abstract
A system and a method are described for monitoring a medical care environment. In one or more implementations, a method includes identifying a first subset of pixels within a field of view of a camera as representing a bed. The method also includes identifying a second subset of pixels within the field of view of the camera as representing an object (e.g., a subject, such as a patient, medical personnel; bed; chair; patient tray; medical equipment; etc.) proximal to the bed. The method also includes determining an orientation of the object within the bed.
