Abstract :
Estimation of 3D surface of a scene from a set of two or more images of that scene taken from the same point of view with different camera focal setting parameters is known as depth from focus/defocus problem. In this paper a system for 3D object reconstruction from endoscopy video is proposed which uses the same focal setting parameters for camera with different points of view of scene. In addition for preventing the undesired vessels dissection during operation, 3D video is augmented with extracted and recognized vessels. The vessels extraction is done with a novel real-time grey image thinning algorithm.
