Kuijpers, E.A. (author)Existing robot vision algorithms are evaluated for application in space for proximity extraction using one camera. Lighting conditions and image formation differ from earth conditions which have implications. An algorithm is derived which is based on the use of run coding, tracking and a least mean error method. Problems concerning hardware...report 1987

Lei, B.J. (author), Hendriks, E.A. (author)We propose a real-time multi-step view reconstruction algorithm and we tune its implementation to a virtual teleconference application. Theoretical motivations and practical implementation issues of the algorithm are detailed. The proposed algorithm can be used to reconstruct novel views at arbitrary poses (position and orientation) in a way...journal article 2002

Van den Heuvel, F.A. (author)Architectural photogrammetry has been practised for more than a century for the documentation of cultural heritage. Nowadays, the emphasis is on the construction of computer models for virtual reality applications. Since the introduction of the computer, and later the digital camera, research in photogrammetry aims at automation. This thesis...doctoral thesis 2003

Bittermann, M. (author), Ciftcioglu, O. (author)Implications of design decisions are hard to oversee for designers. This is the case in particular with respect to decisions, which influence perception related qualities of designs. Such qualities are for example visual openness, visual privacy, and spatial intimacy. They are difficult to measure because of their subjective and soft nature....conference paper 2006

Tadema, J. (author), Koeners, J. (author), Theunissen, E. (author)In the past fifteen years, several research programs have demonstrated potential advantages of synthetic vision technology for manned aviation. More recently, some research programs have focused on integrating synthetic vision technology into control stations for remotely controlled aircraft. The contribution of synthetic vision can be divided...conference paper 2006

Persa, S.F. (author)The focus of this thesis is on studying diverse techniques, methods and sensors for position and orientation determination with application to augmented reality applications. In Chapter 2 we reviewed a variety of existing techniques and systems for position determination. From a practical point of view, we discussed the need for a mobile system...doctoral thesis 2006

Abbas, A. (author), Dias, J. (author)With the increase in fuel prices, flow control technologies are becoming of greater interest as being the means of achieving a technology quantum leap in the next generation of aircrafts, providing the means to achieve significant reduction in drag (fuel burn) and improvements in aircraft performance, shortening thus the path to accomplish the...conference paper 2006

Simonov, A.N. (author), Vdovine, G.V. (author), Loktev, M. (author)We present a prototype of an adaptive intraocular lens based on a modal liquid-crystal spatial phase modulator with wireless control. The modal corrector consists of a nematic liquid-crystal layer sandwiched between two glass substrates with transparent low- and high-ohmic electrodes, respectively. Adaptive correction of ocular aberrations is...journal article 2007

Manta, A. (author)In this master's thesis a framework for the rendering of scenes for 3DTV applications is presented. The goal of our work is to investigate ways to generate virtual views of a scene captured using a relatively small number of real cameras. The approach adopted uses per-pixel operations and therefore is suitable for fast parallel implementation. A...master thesis 2008

Pont, S.C. (author)The appearance of objects in scenes is determined by their shape, material properties and by the light field, and, in contradistinction, the appearance of those objects provides us with cues about the shape, material properties and light field. The latter so-called inverse problem is underdetermined and therefore suffers from interesting...conference paper 2009

Richards, W. (author), Koenderink, J.J. (author), Van Doorn, A. (author)Unlike the Metelli monochrome transparencies, when overlays and their backgrounds have chromatic content, the inferred surface colors may not always be physically realizable, and are in some sense “imaginary.” In these cases, the inferred chromatic transmittance or reflectance of the overlay lies outside the RGB spectral boundaries. Using the...journal article 2009

Karlsson, S.M. (author), Pont, S.C. (author), Koenderink, J.J. (author)The theory of illuminance flow estimation by structure tensors is generalized for oblique viewing of anisotropic texture. An added benefit is that the theory predicts the behavior of unsupervised illuminant tilt estimators. The previous theory is refined with general matrix formulations and compacted by exploiting general properties of the...journal article 2009

Koenderink, J.J. (author)The prior statistics of object colors is of much interest because extensive statistical investigations of reflectance spectra reveal highly non-uniform structure in color space common to several very different databases. This common structure is due to the visual system rather than to the statistics of environmental structure. Analysis involves...journal article 2010
