In this work, effects of stereoscopic view on object recognition and navigation performance of the participants are examined in an indoor Desktop Virtual Reality Environment, which is a two-floor virtual museum having different floor plans and 3D object models inside. This environment is used in two different experimental settings: 1) color-multiplex stereoscopic 3D viewing is provided by colored eye-wear, 2) regular 2D viewing. After the experiment, participants filled a questionnaire that inquires their feeling of presence, their tendency to be immersed and their performance on object recognition and navigation in the environment. Two groups (3D and 2D), each having 5 participants, with equal tendency are formed according to the answers of 'tendency' part, and the rest is evaluated to examine the effects of stereoscopic view. Contrary to our expectations, results show no significant difference between 3D and 2D groups both on feeling of presence and object recognition/navigation performance.


Effects of surface reflectance on local second order shape estimation in dynamic scenes.
Dövencioğlu, Nahide Dicle; Ben-Shahar, O; Doerschner, K (2015-10-01)
In dynamic scenes, relative motion between the object, the observer, and/or the environment projects as dynamic visual information onto the retina (optic flow) that facilitates 3D shape perception. When the object is diffusely reflective, e.g. a matte painted surface, this optic flow is directly linked to object shape, a property found at the foundations of most traditional shape-from-motion (SfM) schemes. When the object is specular, the corresponding specular flow is related to shape curvature, a regime c...
Frequency Domain Scattering Delay Networks for Simulating Room Acoustics in Virtual Environments
De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2011-11-28)
Modelling, simulation and auralisation of room acoustics plays an important role in computer games and virtual reality applications by increasing the level of realism. Accurate simulation of room acoustics is a computationally costly process which is often substituted with artificial reverberators that provide a computationally simpler alternative. However, such systems lack the accuracy and are not in general able to accurately simulate important aspects of room acoustics such as early reflections, source/...
2D-3D feature association via projective transform invariants for model-based 3D pose estimation
Gedik, O. Serdar; Alatan, Abdullah Aydın (2012-01-26)
The three dimensional (3D) tracking of rigid objects is required in many applications, such as 3D television (3DTV) and augmented reality. Accurate and robust pose estimates enable improved structure reconstructions for 3DTV and reduce jitter in augmented reality scenarios. On the other hand, reliable 2D-3D feature association is one of the most crucial requirements for obtaining high quality 3D pose estimates. In this paper, a 2D-3D registration method, which is based on projective transform invariants, is...
Photometric stereo considering highlights and shadows
Büyükatalay, Soner; Halıcı, Uğur; Birgül, Özlem; Department of Electrical and Electronics Engineering (2011)
Three dimensional (3D) shape reconstruction that aims to reconstruct 3D surface of objects using acquired images, is one of the main problems in computer vision. There are many applications of 3D shape reconstruction, from satellite imaging to material sciences, considering a continent on earth or microscopic surface properties of a material. One of these applications is the automated firearm identification that is an old, yet an unsolved problem in forensic science. Firearm evidence matching algorithms rel...
Using multi-modal 3D contours and their relations for vision and robotics
BAŞESKİ, Emre; Pugeault, Nicolas; Kalkan, Sinan; BODENHAGEN, Leon; Piater, Justus H.; KRÜGER, Norbert (Elsevier BV, 2010-11-01)
In this work, we make use of 3D contours and relations between them (namely, coplanarity, cocolority, distance and angle) for four different applications in the area of computer vision and vision-based robotics. Our multi-modal contour representation covers both geometric and appearance information. We show the potential of reasoning with global entities in the context of visual scene analysis for driver assistance, depth prediction, robotic grasping and grasp learning. We argue that, such 3D global reasoni...
