We present trigonometric parallax observations of GD 362 obtained over seven epochs using the MDM 2.4m Hiltner Telescope. The existence of a dust disk around this possibly massive white dwarf makes it an interesting target for parallax observations. The measured parallax for GD 362 places it at a distance of 50.6 −3.1 pc, which implies that its radius and mass are ≈ 0.0106R⊙ and 0.71M⊙, respect...

Recent explosion towards 3D content-enabled devices has brought to light many issues regarding user comfort, depth perception and accessibility in media. One important element that touches these areas is subtitling. We define a pipeline to produce extruded texts for evaluating3D subtitling properties (using traditional 2D depth cues). An evaluation of current 3D tools was carried out, and the c...

W e address the problem of qualitative shape recovery f rom moving surfaces. Our analysis is unique an that we consider specular interreflections and explore the effects of both motion parallax and changes an shading. To study this si tuation we define an image flow field called the reflection flow field, which describes the motion of reflection points and the mot ion of the surface. From a kin...

Parallax Photography: Creating 3D Motions from Stills

We study the first microlensing event toward the Carina spiral arm discovered by the OGLE collaboration. We demonstrate that this long duration event exhibits strong parallax signatures. Additional information from the parallax effect allows us to determine the lens transverse velocity projected onto the Sun-source line to be ∼ 145 km s−1. We also estimate the optical depth, event rate and dura...

Many similarities exist between the perception of depth from binocular stereopsis and that from motion parallax. Moreover, Rogers (1984, cited in, Howard, I. P., & Rogers, B. J. (1995). Binocular vision and stereopsis. Oxford Claridon, New York.) suggests a relationship between an observer's ability to use disparity information and motion parallax information in a depth perception task. To more...

This paper introduces an improved block matching algorithm for the estimation of the parallax field between the left and the right image of a stereo pair. When the block size is small, e.g. for computer vision purposes, traditional block matching alone fails. Most of the small blocks do not expose enough structure to be reliably matched. Therefore, in this paper a parallax field estimated with ...

This article gives an exact expression for parallax adjustments to apparent elevation of objects at finite distances beyond the Earth atmosphere suitable for use at the very low elevation angles required by the Deep Space Network (DSN) Services Preparation Subsystem (SPS) Metric Prediction Generator (MPG). The parallax depends entirely on the astronomical refraction function and does not requir...

As we move through space, stationary objects around us show motion parallax: their directions relative to us change at different rates, depending on their distance. Does the brain incorporate parallax when it updates its stored representations of space? We had subjects fixate a distant target and then we flashed lights, at different distances, onto the retinal periphery. Subjects translated sid...

Light fields preserve angular information which can be retargeted to multi-panel depth displays. Due to limited aperture size and constrained spatial-angular sampling of many light field capture systems, the displayed light fields provide only a narrow viewing zone in which parallax views can be supported. In addition, multi-panel displays typically have a reduced number of panels being able to...
