Articulated Structure From Motion (2005-2006)
Points on a rigid 3D object move in particular ways with respect to each other in the image when the object moves and rotates (known as "structure from motion"). Most research to date has been about single objects or multiple objects that do not interact with each other. This work, however, looks at what the image information tells us about two objects that are coupled together (e.g. by a hinge or ball-and-socket joint). In particular, we show that the way points move with respect to each other can show us exactly where the centre (or axis) of rotation is, even if it is not itself visible in the image.
