Visual Discomfort and Depth-of-Field
i-Perception, 2013 Visual discomfort has been reported for certain visual stimuli and under particular viewing conditions, such as stereoscopic viewing. In stereoscopic viewing, visual discomfort can be caused by a conflict between accommodation and convergence cues that ...

The effect of 2% pilocarpine on depth of field in different time intervals among presbyopic subjects [PDF]
Indian Journal of OphthalmologyPurpose: The aim of this study was to determine the effects of 2% pilocarpine ophthalmic solution on the depth of field and the pupil size of human eye in the presbyopic population. Settings and Design: Prospective experimental study.

Depth of Field Affects Perceived Depth in Stereographs [PDF]
ACM Transactions on Applied Perception, 2014 Although it has been reported that depth of field influences depth perception in nonstereo photographs, it remains unclear how depth of field affects depth perception under stereo viewing conditions. We showed participants stereo photographs with different depths of field using a Wheatstone stereoscope and a commercially available 3D TV.

Depth perception with gaze-contingent depth of field [PDF]
Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2014 Blur in images can create the sensation of depth because it emulates an optical property of the eye; namely, the limited depth of field created by the eye's lens. When the human eye looks at an object, this object appears sharp on the retina, but objects at different distances appear blurred.

Evaluation of Depth of Field for depth perception in DVR [PDF]
2013 IEEE Pacific Visualization Symposium (PacificVis), 2013 In this paper, we present a user study on the use of Depth of Field for depth perception in Direct Volume Rendering. Direct Volume Rendering with Phong shading and perspective projection is used as the baseline. Depth of Field is then added to see its impact on the correct perception of ordinal depth.

ACM Transactions on Graphics, 2009 Optical systems used in photography and cinema produce depth-of-field effects, that is, variations of focus with depth. These effects are simulated in image synthesis by integrating incoming radiance at each pixel over the lense aperture. Unfortunately, aperture integration is extremely costly for defocused areas where the incoming radiance has high ...

Vari-Focal Light Field Camera for Extended Depth of Field [PDF]
Micromachines, 2021 The light field camera provides a robust way to capture both spatial and angular information within a single shot. One of its important applications is in 3D depth sensing, which can extract depth information from the acquired scene.
