(author), van Rest, J.H.C. (author)In the security domain, cameras are important to assess critical situations. Apart from fixed surveillance cameras we observe an increasing number of sensors on mobile platforms, such as drones, vehicles and persons. Mobile cameras allow rapid and local deployment, enabling many novel applications and effects, such as the reduction of violence...conference paper 2015

(author)Person tracking across non-overlapping cameras and other types of video analytics benefit from spatial calibration information that allows an estimation of the distance between cameras and a relation between pixel coordinates and world coordinates within a camera. In a large environment with many cameras, or for frequent ad-hoc deployments of...conference paper 2015

(author)Background: Intraoperative nerve localization is of great importance in surgery. In certain procedures, where nerves show visual resemblance to surrounding adipose tissue, this can be particularly challenging for the human eye. An example of such a delicate procedure is thyroid and parathyroid surgery, where iatrogenic injury of the recurrent...article 2014

Alic, L. (author), Niessen, W.J. (author), Veenland, J.F. (author)Background:Many techniques are proposed for the quantification of tumor heterogeneity as an imaging biomarker for differentiation between tumor types, tumor grading, response monitoring and outcome prediction. However, in clinical practice these methods are barely used. This study evaluates the reported performance of the described methods and...article 2014

Dijk, J. (author), Bijl, P. (author), van den Broek, S.P. (author), van Eijk, A.M.J. (author)Our world is constantly changing, and this has its effect on worldwide military operations. For example, there is a change from conventional warfare into a domain that contains asymmetric threats as well. The availability of high-quality imaging information from Electro-Optical (EO) sensors is of high importance, for instance for timely...conference paper 2014

van Eekeren, A.W.M. (author), Dijk, J. (author), Burghouts, G. (author)Airborne platforms are recording large amounts of video data. Extracting the events which are needed to see is a timedemanding task for analysts. The reason for this is that the sensors record hours of video data in which only a fraction of the footage contains events of interest. For the analyst, it is hard to retrieve such events from the...conference paper 2014

Lefter, I. (author), Burghouts, G.J. (author), Rothkrantz, L.J.M. (author)Stressful situations are likely to occur at human operated service desks, as well as at human-computer interfaces used in public domain. Automatic surveillance can help notifying when extra assistance is needed. Human communication is inherently multimodal e.g. speech, gestures, facial expressions. It is expected that automatic surveillance...article 2014

Burghouts, G.J. (author), Eendebak, P.T. (author), Bouma, H. (author), Hove, R.J.M. (author)In this paper, we summarize how the action recognition can be improved when multiple views are available. The novelty is that we explore various combination schemes within the robust and simple bag-of-words (BoW) framework, from early fusion of features to late fusion of multiple classifiers. In new experiments on the publicly available IXMAS...conference paper 2014

van Eekeren, A.W.M. (author), Huebner, C.S. (author), Dijk, J. (author), Schutte, K. (author), Schwering, P.B.W. (author)Atmospheric turbulence is a well-known phenomenon that diminishes the recognition range in visual and infrared image sequences. There exist many different methods to compensate for the effects of turbulence. This paper focuses on the performance of two software-based methods to mitigate the effects of low-And medium turbulence conditions. Both...conference paper 2014

Bouma, H. (author), van Rest, J.H.C. (author), Burghouts, G.J. (author), Schutte, K. (author), Baan, J. (author)To improve security in crowded environments, such as airports, shopping malls and railway stations, the number of surveillance cameras (CCTV) is rapidly increasing. However, the number of human operators remains limited and only a selection of the video streams can be observed. This makes it hard for an operator to be proactive. This paper gives...article 2014

Sanromà, G. (author), Patino, L. (author), Burghouts, G.J. (author), Schutte, K. (author), Ferryman, J. (author)We present a method for the recognition of complex actions. Our method combines automatic learning of simple actions and manual definition of complex actions in a single grammar. Contrary to the general trend in complex action recognition, that consists in dividing recognition into two stages, our method performs recognition of simple and...article 2014

(author)Recently, we have shown that connecting live three-dimensional (3D) monitors to all three available Da Vinci® robot (Intuitive) generations improved the impression of shared perception for the whole surgical team. Standardized dry lab experiments revealed that delicate teamwork was faster (up to 40%) when using the 3D monitor [1]. We now studied...conference paper 2014

(author)Theft of cargo from a truck or attacks against the driver are threats hindering the day to day operations of trucking companies. In this work we consider a system, which is using surveillance cameras mounted on the truck to provide an early warning for such evolving threats.

(author)In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by...article 2014

Ruizenaar, M.G.H. (author), Kemp, R.A.W. (author)In this paper a method is presented that allows for bias compensation of low-cost MEMS inertial sensors. It is based on the use of two sets of inertial sensors and a rotation mechanism that physically rotates the sensors in an alternating fashion. After signal processing, the biases of both sets of sensors are estimated and compensated for,...conference paper 2014

(author)Long-term tracking is important for maritime situational awareness to identify currently observed ships as earlier encounters. In cases of, for example, piracy and smuggling, past location and behavior analysis are useful to determine whether a ship is of interest. Furthermore, it is beneficial to make this assessment with sensors (such as...conference paper 2014
