title: Intra-operative registration for image enhanced endoscopic sinus surgery using photo-consistency.
abstract: The purpose of this paper is to present an intensity based algorithm for aligning 2D endoscopic images with virtual images generated from pre-operative 3D data. The proposed algorithm uses photo-consistency as the measurement of similarity between images, provided the illumination is independent from the viewing direction.
