We evaluated the ability of emmetropic and myopic observers to detect and discriminate blur across the retina under monocular or binocular viewing conditions. We recruited 39 young (23-30 years) healthy adults (n = 19 myopes) with best-corrected visual acuity 0.0 LogMAR (20/20) or better in each eye and no binocular or accommodative dysfunction. Monocular and binocular blur discrimination thres...

The human face is one of the most interesting subjects involved in numerous applications. Significant progress has been made towards the image deblurring problem, however, existing generic deblurring methods are not able to achieve satisfying results on blurry face images. The success of the state-of-the-art image deblurring methods stems mainly from implicit or explicit restoration of salient ...

To use a projector anytime anywhere, a lot of projectorcamera based approaches have been proposed. In this paper, we focus on a focal correction technique, one of projector-camera based approaches, reduces an effect of defocus blur which occurs when a screen is located out of projector’s depth-of-field. We propose a novel method for estimating projector defocus blur on a planar screen without a...

Abstract This paper is a contribution to the philosophical debate on visual blur from relationalist perspective. At same time, it offers methodological reflection adequacy of explanations phenomenal similarities and differences among perceptual experiences. The seeing blurrily has been shaped by two implicit assumptions concerning our between experiences other I call those into question, argue ...

Perceived blur is an important measure of image quality and clinical visual function. The magnitude of image blur varies across space and time under natural viewing conditions owing to changes in pupil size and accommodation. Blur is frequently studied in the laboratory with a variety of digital filters, without comparing how the choice of filter affects blur perception. We examine the percepti...

Knowledge regarding successive blur discrimination thresholds (i.e., equiblur zones) in depth and across the near retinal periphery, and their relation to blur detection (i.e., depth-of-focus), remains unknown. The blur detection threshold and four successive blur discrimination thresholds were measured psychophysically at the fovea, as well as at retinal eccentricities of 0.25 degrees , 2 degr...

The removal of motion blur induced into images is currently an active eld of research. The analysis of motion de-blur algorithms has shown, that they perform di erently on synthetic and real motion blur. Therefore we have build an apperatus which allows us to produce pictures with de ned motion blur induced, so we can study these possible di erences. In this paper we focus on clearly visible li...
