Automated identification, pose and size estimation, and contour extraction of diaphyseal bone fragments can greatly improve the usability of a computer-assisted fluoroscopy-based navigation system for long bone fracture reduction. In this paper, a two step solution is proposed. The pose and size of a diaphyseal fragment are estimated through 3D morphable object fitting using a parametric cylinder...
A common manifestation of osteoarthritis (OA) of the knee is the morphological degeneration of articular cartilage. In vivo magnetic resonance imaging (MRI) offers the potential to visualize and analyze quantitatively morphology such as cartilage thickness and volume. The purpose of this work was the development of new image processing techniques and application of existing ones for the intra and...
