This paper presents a computer vision based technique for 
object registration, real-time tracking, and image overlay. The 
capability can be used to superimpose registered medical images 
such as those from CT or MRI onto a video image of a patient's body. 
Real-time object registration enables an image to be overlaid 
consistently onto objects even while the objects and cameras 
viewing it are moving. Object registration is composed of feature 
tracking, feature correspondence, and pose calculation of objects. 
This technique is based on geometric models of objects, but it can 
be extended so that some image overlay is possible without a prior 
model of the object.
