1. A system comprising:
a processor; and
a memory in communication with the processor, the memory containing program instructions that, when executed by the processor, are configured to cause the processor to perform a method, the method comprising:
receiving an infrared (IR) image;
receiving a depth map associated with the IR image;
applying one or more filters to the IR image based on a set of parameters, wherein the one or more filters are configured to reduce local brightness contrast from absorbance and reflectance properties of materials on a subject;
generating a 2D pose for the subject based on the filtered IR image; and
generating a 3D pose by correlating the 2D pose to the depth map.
