The popularity of 3D video is increasing daily due to the availability of low-cost 3D televisions and high-speed Internet access. However, currently the contents of 3D video can be distributed illegally without any protection. For views generated using a depth-image-based rendering technique, not only the left and right views can be distributed as 3D content, but also the center, left, or right views...
Multi-modal medical image registration provides complementary information from the fusion of various medical imaging modalities. This paper presents a volume based multi-modal affine registration algorithm to register images acquired using different magnetic resonance imaging (MRI) modes. In the proposed algorithm, the sum-of-conditional variance (SCV) similarity measure is used. The SCV is considered...
Total hip arthroplasty or THA is a surgical procedure for the relief of significant disabling pain caused by osteoarthritis or hip fracture. Knowledge of the 3D kinematics of the hip during specific functional activities is important for THA component design. In this paper we compare kinematic measurements obtained by a new 2D-3D registration algorithm with measurements provided by the gold standard...
Ultrasonic positioning systems are used for various types of applications across a wide variety of fields, including robot navigation, device location and pose estimation. Current ultrasonic positioning systems have limitations when simultaneously locating multiple transmitters in three-dimensional (3D) space using narrowband ultrasonic transducers. They are also unable to calculate a transmitter's...
Typically, indoor positioning systems require higher precision than outdoor positioning systems. Outdoor positioning technologies such as GPS provide poor accuracy in indoor environments due to signal attenuation by the building fabric. In indoor environments, commercial motion-capture systems are proficient at measuring the 3D position of an object precisely. The main disadvantages of this method...
