purpose: to determine anterior chamber depth (ac depth) changes during a 6 month period after phacoemulsification cataract surgery and foldable intraocular lens (iol) implantation. methods: in a cross-sectional study, 85 eyes of 85 patients were evaluated for ac depth and capsulo-rrhexis size one and six months after the procedure. results: patients included 44 male and 41 female subjects with ...

the changes in density and biomass of macrobenthos were seasonally investigated from winter 2005 till fall 2006 in southern caspian sea. samples were taken with a 225cm2 van veen grab from depths of 7 and 20 meters along two transects: line 8 area (western part) and radio darya area (eastern part). totally, 5 classes of macrobenthos were identified of which the most abundant populations were po...

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...

the study aimed at investigating whether the retention of vocabulary acquired incidentally is dependent upon the amount of task-induced involvement. immediate and delayed retention of twenty unfamiliar words was examined in three learning tasks( listening comprehension + group discussion, listening comprehension + dictionary checking + summary writing in l1, and listening comprehension + dictio...

in this study digital image correlation (dic) technique combined with a high speed video system was used to predict movement of particles in a water model. comparing with particle-image velocimetry (piv) technique, it provides a low cost alternative approach to visualize flow fields and was successfully employed to predict the movement of particles in a water model at different submergence dept...

Multiview video in “texture-plus-depth” format enables decoder to synthesize freely chosen intermediate views for enhanced visual experience. Nevertheless, transmission of multiple texture and depth maps over bandwidthconstrained and loss-prone networks is challenging, especially for conferencing applications with stringent deadlines. In this paper, we examine the problem of loss-resilient codi...
