Abstract
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. Introduction Computer vision has found applications in surgery: computer-assisted detection of anatomical and functional lesions, 3D representation and analysis of brain energy metabolism and so on[1][2]. They are, however, limited mostly to off-line presurgical analysis and processing. Due to the significant improvements in comput...
