Subject identification systems and methods

A system comprising one or more processors and memory operably coupled with the one or more processors, wherein the memory stores instructions that, in response to execution of the instructions by one or more processors, cause the one or more processors to perform the following operations:

• acquiring one or more digital images that depict a subject in an area, where the area comprises a waiting room, and the one or more digital images that depict the waiting room are acquired using a camera that is configured to capture the waiting room;
• detecting, as one or more detected face images, one or more portions of the one or more digital images that depict a face of the subject;
• comparing features of each of the one or more detected face images with features of each of a set of subject reference templates associated with a given subject in a subject reference database, wherein the subject reference database stores subject reference templates related to a plurality of subjects;
• based on the comparing, selecting a subject reference template from the set of subject reference templates associated with the given subject;
• determining one or more similarity measures between a given detected face image of the one or more detected face images and the selected subject reference template;
• determining an identity of the subject based on the one or more similarity measures, and
• acquiring one or more vital signs and/or physiological parameters of the subject from a vital signs acquisition camera.

At least one non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by one or more processors, cause the one or more processors to perform the following operations:

• acquiring one or more digital images that depict a subject in an area, wherein the area comprises a waiting room, and the one or more digital images that depict the waiting room are acquired using a camera that is configured to capture the waiting room;
• detecting, as one or more detected face images, one or more portions of the one or more digital images that depict a face of the subject;
• comparing features of each of the one or more detected face images with features of each of a set of subject reference templates associated with a given subject in a subject reference database, wherein the subject database stores subject reference templates related to a plurality of subjects;
• based on the comparing, selecting a subject reference template from the set of subject reference templates associated with the given subject;
• determining one or more similarity measures between a given detected face image of the one or more detected face images and the selected subject reference template;
• determining an identity of the subject based on the one or more similarity measures, and
• acquiring one or more vital signs and/or physiological parameters of the subject from a vital signs acquisition camera.
