Among monocular depth cues, ocular parallax (first described formally by Brewster in 1844) remains mostly unknown, its role in perception still not investigated scientifically. Given that every single eye movement induces ocular parallax, it is a potentially useful depth cue. This paper is an attempt to revive interest in the topic. As a monocular depth cue, ocular parallax naturally leads us t...

It is well known that Intercrystal scattering (ICS) and the parallax effect are two major resolution limiting parameters in current PET detector designs with block detectors. More recently for the purpose of resolution recovery, investigators and manufacturers have attempted to accurately model these effects into the image reconstruction task. In this study we utilized the MCNP4C Monte Carlo co...

This study compared two different radiographic techniques for localization of impacted maxillary canines: vertical parallax (from a panoramic and a maxillary anterior occlusal radiograph) and magnification (from a single panoramic radiograph). The radiographs and the information regarding the impacted canines were obtained retrospectively from records of patients treated in the Day Stay Unit of...

Image registration is a fundamental task in computer vision because it can significantly contribute to high-level computer vision and benefit numerous practical applications. Though a lot of image registration techniques exist in literature, there is still a significant amount of research to be conducted because there are a lot of issues that need to be solved such as the parallax problem. The ...

Motion parallax is the optical change of the visual field of an observer which results from a change of his viewing position. It is often denned as the set of "apparent motions" of stationary objects which arise during locomotion. Psychologists assert that it is a "cue" for perceiving the depth of the objects, but the optical fact of motion parallax must be distinguished from its capacity to in...

The ability to detect surfaces was studied in a multiple-cue condition in which binocular disparity and motion parallax could specify independent depth configurations. On trials on which binocular disparity and motion parallax were presented together, either binocular disparity or motion parallax could indicate a surface in one of two intervals; in the other interval, both sources indicated a v...

The ability to detect significant change in images is reduced when there is parallax. Fixed objects above or below the ground plane displace from their true position by an amount that depends on their height and the look angle of the sensor, reducing background cancellation and limiting the effectiveness of change detection. A method for reducing the effect of parallax shifts using dynamic time...

We analyze the Galactic bulge microlensing event MOA 2003-BLG-37. Although the Einstein timescale is relatively short, tE 1⁄4 43 days, the light curve displays deviations consistent with parallax effects due to the Earth’s accelerated motion. We show that the 2 surface has four distinct local minima that are induced by the ‘‘jerk-parallax’’ degeneracy, with pairs of solutions having projected E...
