van Leeuwen, C.J. (author), van Huis, J.R. (author), Baan, J. (author)Wide Area Motion Imagery (WAMI) enables image based surveillance of areas that can cover multiple square kilometers. Interpreting and analyzing information from such sources, becomes increasingly time consuming as more data is added from newly developed methods for information extraction. Captured from a moving Unmanned Aerial Vehicle (UAV), the...conference paper 2016

Lefter, I. (author), Burghouts, G.J. (author), Rothkrantz, L.J.M. (author)This paper investigates how speech and gestures convey stress, and how they can be used for automatic stress recognition. As a first step, we look into how humans use speech and gestures to convey stress. In particular, for both speech and gestures, we distinguish between stress conveyed by the intended semantic message (e.g. spoken words for...article 2016

Eendebak, P.T. (author), Schoen, E.D. (author)We study the design of two-level experiments with N runs and n factors large enough to estimate the interaction model, which contains all the main effects and all the two-factor interactions. Yet, an effect hierarchy assumption suggests that main effect estimation should be given more prominence than the estimation of two-factor interactions....article 2016

Kruithof, M.C. (author), Bouma, H. (author), Fischer, N.M. (author), Schutte, K. (author)Object recognition is important to understand the content of video and allow flexible querying in a large number of cameras, especially for security applications. Recent benchmarks show that deep convolutional neural networks are excellent approaches for object recognition. This paper describes an approach of domain transfer, where features...conference paper 2016

Baart, T.A. (author), Eendebak, P.T. (author), Reichl, C. (author), Wegscheider, W. (author), Vandersypen, L.M.K. (author)We report the computer-automated tuning of gate-defined semiconductor double quantum dots in GaAs heterostructures. We benchmark the algorithm by creating three double quantum dots inside a linear array of four quantum dots. The algorithm sets the correct gate voltages for all the gates to tune the double quantum dots into the single-electron...article 2016

(author), van Rest, J. (author)Deception detection is valuable in the security domain to distinguish truth from lies. It is desirable in many security applications, such as suspect and witness interviews and airport passenger screening.

Dijk, J. (author), Schutte, K. (author), Nieuwenhuizen, R.P.J. (author)Visual and infrared imagery is degraded by turbulence caused by atmospheric conditions. Because the degradation gets worse for longer distances, turbulence especially hampers long range observation. At sea this turbulence affects classification and identification of ships and other objects. State of the art software based processing algorithms...conference paper 2016

(author)Airborne platforms, such as UAV's, with Wide Area Motion Imagery (WAMI) sensors can cover multiple square kilometers and produce large amounts of video data. Analyzing all data for information need purposes becomes increasingly labor-intensive for an image analyst. Furthermore, the capacity of the datalink in operational areas may be inadequate...conference paper 2015

Bouma, H. (author), Eendebak, P.T. (author), Schutte, K. (author), Azzopardi, G. (author), Burghouts, G.J. (author)Object recognition and localization are important to automatically interpret video and allow better querying on its content. We propose a method for object localization that learns incrementally and addresses four key aspects. Firstly, we show that for certain applications, recognition is feasible with only a few training samples. Secondly, we...conference paper 2015

(author)In colorectal surgery, detecting ureters and mesenteric arteries is of utmost importance to prevent iatrogenic injury and to facilitate intraoperative decision making. A tool enabling ureter- and artery-specific image enhancement within (and possibly through) surrounding adipose tissue would facilitate this need, especially during laparoscopy....article 2015

de Boer, M.H.T. (author), Brandt, P. (author), Sappelli, M. (author), Daniele, L.M. (author), Schutte, K. (author), Kraaij, W. (author)One of the challenges in the field of content-based image retrieval is to bridge the semantic gap that exists between the information extracted from visual data using classifiers, and the interpretation of this data made by the end users. The semantic gap is a cascade of 1) the transformation of image pixels into labelled objects and 2) the...article 2015

de Boer, M.H.T. (author), Schutte, K. (author), Kraaij, W. (author)A common approach in content based video information retrieval is to perform automatic shot annotation with semantic labels using pre-trained classifiers. The visual vocabulary of state-of-the-art automatic annotation systems is limited to a few thousand concepts, which creates a semantic gap between the semantic labels and the natural language...article 2015
