Introduction We present an image-guided surgical microscope system using augmented reality image overlays added onto one of the views of the operating microscope. With this system, segmented objects, outlines of risk regions, access pathways or 3D objects, previously extracted from preoperative tomographic images can be directly displayed as augmented reality overlays on the microscope image. R...

We introduce a novel method for constructing polyhedra by blending together two or more existing polyhedra, using a dualization method. The method results in a Minkowski sum, analogous to that of overlay tilings [5], which uses a topological dual operation to create tilings from a network (a graph embedded in a plane). This paper extends that method to networks on the surface of the unit sphere...

Abstract Although Voice Assistants are ubiquitously available for some years now, the interaction is still monotonous and utilitarian. Sound design offers conceptual methodological research to auditive interfaces. Our work aims complement supplement voice with sonic overlays enrich user experience. Therefore, we followed a user-centered process develop sound library weather forecasts based on e...

Background: The bite injury or mark is examined as corroborative evidence in serious crimes such rape, murder, robbery, and other forms of physical sexual violence. goal this study was to comparatively evaluate the accuracy overlays made with a digital, two-dimensional method compared those by directly tracing marks using images obtained photocopier. Materials Methods: A total 61 participants w...

In real-world peer-to-peer applications, the scalability of data lookup is heavily affected by network artifacts. A common solution to improve scalability, robustness and security is to increase the local properties of nodes, by clustering them together. This paper presents a framework which allows for the development of distributed applications on top of interconnected overlay network. Here, m...

Vegetation mapping of national park units in the southeastern United States is being undertaken by the Center for Remote Sensing and Mapping Science at the University of Georgia. Because of the unique characteristics of the individual parks, including size, relief, number of photos and availability of ground control, different approaches are employed for converting vegetation polygons interpret...

An increasingly common approach to data analysis involves using information dashboards to visually compare changing data. However, layout constraints coupled with varying levels of visualization literacy among dashboard users make facilitating visual comparison in dashboards a challenging task. In this paper, we evaluate variants of bar charts, one of the most prevalent class of charts used in ...

PlanetLab testbed is widely used to evaluate protocols and applications under realistic Internet conditions, but this realism comes at the cost of uncontrolled topology and traffic behavior. The use of overlay networks on PlanetLab can solve this problem by giving more control to the experimenter. However, manually creating such overlays is far from simple, and existing solutions are either not...
