1. A computing system for processing images, comprising: a 3-D imaging system, the 3-D imaging system generates at least one depth map from at least one image of a first person in an application during a calibration process of the application; an object detector, the object detector identifies a body part of the first person in the at least one depth map; an anomaly detector, the anomaly detector, responsive to the object detector, identifies, from the at least one depth map, an anomaly in the body part of the first person, the anomaly in the body part of the first person comprising: (a) a logical gap anomaly which represents a first object of the body part of the first person appearing to be further from the 3-D imaging system than the first object actually is due to a lower reflective property of the first object, where the first object is identified by pixel depths which are less than pixel depths of an adjacent region of the first object or (b) a logical protrusion anomaly which represents the first object appearing to be closer to the 3-D imaging system than the first object actually is due to a higher reflective property of the first object, where the first object is identified by pixel depths which are greater than pixel depths of an adjacent region of the first object; and an anomaly marker, the anomaly marker, responsive to the anomaly detector, generates a marker which identifies the anomaly in the body part of the first person, the anomaly marker forwards the marker which identifies the anomaly in the body part of the first person to the object detector and the object detector, in response to the anomaly marker, subsequently uses the marker which identifies the anomaly in the body part of the first person as a template to identify a future occurrence of the body part of the first person in a series of depth maps after the calibration process.
