In medical imaging, 2D-3D registration approaches have been used for image guided surgery (IGS) and pre-, post-operative measurement of joint kinematics. The application addressed in this paper is the registration of single-plane 2D fluoroscopy images to 3D Computed Tomography (CT) data. A limitation of previously proposed 2D-3D registration algorithms has been an inability to register images with...
Building a photorealistic, 3D model of an object or a complete scene from image-based methods is a fundamental problem in computer vision, and has many applications in robotic perception, navigation, exploration and mapping. In this paper, we extend current state-of-the-art in the computation of depth maps by presenting an accurate and computationally efficient iterative hierarchical algorithm for...
2D-3D image registration has become an important tool in many clinical applications such as image-guided surgery and the kinematic analysis of bones in knee and ankle joints. A limitation of this approach is the need to recalculate the voxel values in the 3D volume for every iteration of the registration procedure. In this paper we propose a new 2D-3D image registration algorithm which uses the projected...
