The provision of stereo images to facilitate depth perception by stereopsis is one key aspect of many Virtual Reality installations and there are many technical approaches to do so. However, differences in visual capabilities of the user and technical limitations of a specific set-up might restrict the spatial range in which stereopsis can be facilitated. In this paper, we transfer an existent ...

Thermodynamic and dynamic analyses of a variable speed reciprocating compressor have been conducted to investigate performance changes and some data related to the reliability problems such as valve velocity, PV value, bearing loci, Sommerfeld number, minimum film thickness etc. The first law of thermodynamics, continuity equations, valve dynamic equations and Helmholtz resonator method were us...

Vergence eye movements are a key factor in stereoscopic depth perception. In this brief review I will outline work at York University on select aspects of the relation between vergence and stereopsis, sensory fusion and depth constancy.

We introduce a digital hologram generation of a real 3D object captured by a depth camera. The depth camera is employing a time multiplexed concept for color and depth image acquisition in a single chip sensor. The 3D information, point cloud, corresponding to the real scene, is extracted from taken image pairs, a gray texture and a depth map by a depth camera. The extracted point cloud is used...

In this paper we will present the concept of a modular three dimensional broadcast chain, that allows for an evolutionary introduction of depth perception into the context of 2D digital TV. The work is performed within the framework of the European Information Society Technologies (IST) project “Advanced Three-dimensional Television System Technologies” (ATTEST), bringing together the expertise...

In this paper, we present a system to redistribute computational power in plane sweeping. Plane sweeping allows the generation of novel viewpoints of a scene by testing different depth hypotheses across input cameras. Typical plane sweeping approaches incorporate a uniform depth plane distribution to investigate different depth hypotheses to generate a depth map. When the scene consists of a sp...
