1. A method comprising the steps of: receiving image data from a millimeter wave imaging device comprising at least one scan of a scene, enhancing the image data, using at least one computing device, using at least one enhancement method, thereby creating enhanced image data comprising a plurality of enhanced image pixels; evaluating the enhanced image data, using the at least one computing device, using at least one identification method, thereby identifying at least one subject within the enhanced image data; separating the at least one subject from a background within the enhanced image data, using the at least one computing device, using at least one separation method; enhancing contrast of the at least one subject within the enhanced image data, using the at least one computing device, using at least one enhancement method, thereby creating enhanced contrast image data; detecting concealed physical objects associated with the at least one subject within the enhanced contrast image data, using the computing device, using at least one detection method, thereby detecting at least one concealed physical object associated with the at least one subject; displaying a representation of the at least one subject and the at least one concealed physical object on a display device.
