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 ...

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 ...

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.

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.

Subjective method of refractometry and depth of focus
Journal of Optometry, 2012 Purpose: To study the impact of the depth of focus on subjective refraction and distribution of myopic and hyperopic refractions. Methods: A total of 450 eyes of 305 subjects in the age range of 23–34 years were recruited for the study. A distribution of

Multi-Object Deep-Field Digital Holographic Imaging Based on Inverse Cross-Correlation
Applied Sciences, 2023 To address the complexity of small or unique reconstruction distances in digital holography, we propose an inverse cross-correlation-based algorithm for the digital holographic imaging of multiplanar objects with a large depth of field. In this method, a
