Ultrasound is an imaging modality which provides spatial measurements of subsurface targets during surgical interventions without the radiation or logistical concerns of CT or MR imaging, respectively. However, image interpretation is known to be a challenging task without other sources of information. This is not only because of the noise characteristics of ultrasound, but also because manipulation and compression of soft tissue during imaging with an ultrasound probe can distort the size and p...

Previous research in computer science shows that developers spend a large fraction of their time navigating through source code. Improving developers’ effectiveness in navigating code thus should yield significant productivity improvements. Pre vious research in a number of fields suggests that a more breadth-first approach to problem solving should be more successful than a more depth-first approach. Unfortunately, modern Integrated Development Environments (IDEs) do not sup port a breadth-firs...

Psychology / Ph.D. / Navigation proficiency - the ability to find and recall new and familiar locations - varies widely among individuals (e.g., Schinazi, Epstein, Nardi, Newcombe, & Shipley, 2013; Weisberg, Schinazi, Newcombe, Shipley, & Epstein, 2014). The cognitive processes that support effective navigation have been theoretically sketched out (e.g., Wolbers & Hegarty, 2010), but how do those processes contribute to aspects of and individual differences in navigation behavior? Using a virtua...

La navigation par satellite prend un virage très important ces dernières années, d'une part par l'arrivée imminente du système Européen GALILEO qui viendra compléter le GPS Américain, mais aussi et surtout par le succès grand public qu'il connaît aujourd'hui. Ce succès est dû en partie aux avancées technologiques au niveau récepteur, qui, tout en autorisant une miniaturisation de plus en plus avancée, en permettent une utilisation dans des environnements de plus en plus difficiles.

Over the last years researchers proposed numerous indoor localisation and navigation systems. However, solutions that use WiFi or Radio Frequency Identification require infrastructure to be deployed in the navigation area and infrastructureless techniques, e.g. the ones based on mobile cell ID or dead reckoning suffer from large accuracy errors. In this Thesis, we present a novel approach of infrastructure-less indoor navigation system based on computer vision Structure from Motion techniques. W...

An Inertial Navigation System (INS) can individually produce the navigation data, i.e.position, velocity, of the aircraft without any help or aid. However, a large number of errors are ntroduced by sensors causing to an unacceptable drift in the output. Because of this reason, external aids are used to correct INS. Using these aids an integrated navigation structure is developed. In an integrated navigation system, INS output is used to alculate current navigation states / aid is used to suppl...

Processing and interpretation of visual content is essential to many systems and applications. This requires knowledge of how the content is sensed and also what is sensed. Such knowledge is captured in models which, depending on the application, can be very advanced or simple. An application example is scene reconstruction using a camera; if a suitable model of the camera is known, then a model of the scene can be estimated from images acquired at different, unknown, locations, yet, the quality...

Navigation in complex environments requires selection of appropriate actions as a function of local cues. To gain a quantitative and mechanistic understanding of zebrafish thermal navigation, we have developed a novel assay that requires animals to rely exclusively on thermosensory information in the absence of other cues such as vision or mechanosensation. We show that zebrafish use both absolute and relative temperature information to restrict their locomotor trajectories to a preferred temper...

We have designed and demonstrated a new class of medical navigation methods that use the fingerprint-like biometrically distinct ultrasound echo patterns produced by different locations in tissue. As an example of this new biometric navigation approach, we have constructed and tested a system that uses ultrasound data to achieve prospective motion compensation in MRI, especially for respiratory motion during interventional MRI procedures in moving organs such as the liver. The ultrasound measure...

The invention of the airship and subsequently, at the beginning of the last century, of the airplane made legislators think about comprehensive legal regulation of navigation in airspace. The scope of the first laws and international treaties was limited to the regulation of navigation performed by a vehicle deriving its support in the air from reactions against the air, either aerostatic or aerodynamic. As technical developments have advanced, new vehicles capable of navigating in airspace have...

The trackball metaphor is exploited in many applications where volumetric data needs to be explored. Although it provides an intuitive way to inspect the overall structure of objects of interest, an in-detail inspection can be tedious - or when cavities occur even impossible. Therefore we propose a context-aware navigation technique for the exploration of volumetric data. While navigation techniques for polygonal data require information about the rendered geometry, this strategy is not sufficie...

The concept of augmented reality has existed since the 60’s. In this thesis it has been investigated if navigation using a mobile device would benefit, from a usability perspective, if the navigational data were presented using augmented reality instead of a standardized map. The usability principles from which the applications were evaluated are learnability, user satisfaction, efficiency and effectivity. An AR prototype was developed and tested against a standard map, in the form of Google Map...

A method is proposed for determining the motion of a body relative to a fixed environment using the changing image seen by a camera attached to the body. The optical flow in the image plane is the input, while the instantaneous rotation and translation of the body are the output. If optical flow could be determined precisely, it would only have to be known at a few places to compute the parameters of the motion. In practice, however, the measured optical flow will be somewhat inaccura...
