Too Long; Didn't Read
Facebook's PIFuHD uses a 2D image to re-construct a high-res 3D model of yourself. This is state-of-the-art, as previous algorithms couldn't capture details like fingers, facial features, and clothing folds. This can all be done from a single, smartphone-quality photo. The technology could be expanded to enable 3D MRIs, CTs, or ultrasonic images. The possibilities are endless for many applications in medical imaging and virtual reality.
