Purpose: To evaluate the integrity of lateral soft tissue in varus osteoarthritis knee by comparing mechanical axis under stress during navigation-assisted total arthroplasty before and after compensating for a bone defect with implant. Methods: Sixty-six knees that underwent were investigated. The operated was evaluated manual immediately exposure implantation. correlation between each value d...

<p>With the rapid development of mechatronics, systems in package (SiP), particular MPU-9250 inertial measurement Unit 9DOF (MPU-6050 6DOF and AK8963 3DOF), are becoming ubiquitous applications for autonomous navigation purposes. Nevertheless, they suffer from some accuracy problems related to axis misalignment, disturbances, deviation over time that make them unable work autonomously a l...

Shape skeletonization (i.e., medial axis extraction) is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. In this paper, we expand the use of diffusion equations combined with distance field information to approximate medial axes of arbitrary 3D solids represented by polygonal meshes based on their differential propert...

Abstract Traditional rotational inertial navigation systems are based on rotation around one or two sensitive axes of sensors. However, as the and sensors lie along same direction, it is difficult to modulate relative error sensor in axial direction. This paper proposes a dual-axis scheme diagonal measurement unit (IMU) body. The selects body three orthogonal IMU horizontal axis, sets vertical ...

An adaptive algorithm to compute the medial axis transform of 2D polygonal domains with arbitrary genus is presented. The algorithm is based in the reenement of a coarse medial axis transform by subdividing the domain adaptively. The algorithm provides the medial axis represented by a set of triangles of a predeened size and the closest boundary element. Examples of results are also presented t...

The medial axis of an image pattern is the loci of all inscribed disks that touch two or more boundary points without crossing any of the boundaries. The medial axis transform (MAT) is a powerful representation for objects with inherent symmetry or near-symmetry. The medial axis of 2-D image patterns provides a conceptual design base, with transition to a detailed design occurring when the radi...
