A New Representation of the Contrast Sensitivity Function for Human Vision
نویسندگان
چکیده
This paper presents a new mathematical representation of the contrast sensitivity function for the human visual system. It is based on optimal smoothing spline ts to vertical and oblique contrast sensitivity measurements. Unlike most of the approximations in current use, which assume isotropy, this new representation incorporates the dependence on orientation revealed by the measurements. One of the uses of the representation is demonstrated by applying it to an example lumi-nance eld.

Background and purpose: Threshold contrast sensitivity could be considered as an important indicator of visual function in thalassemic patients. In this study the threshold of contrast sensitivity was investigated in patients with major and minor thalassemia and normal individuals. Material & methods: This cross-sectional study was conducted in 30 patients of thalassemia major (Desferal depen...
متن کاملStudy of Optical Models Regarding the Human Eye
Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...

Background: The major limitation in human vision is refractive error. Auxiliary equipment and methods for these people are not always available. In addition, limited range of accommodation in adult people when switching from a far point to a near point is not simply possible. In this paper, we are looking for solutions to use the facilities of digital image processing and displaying to improve ...

Background and Objective: Car accidents are the second leading cause of mortality in Iran. For safe driving, drivers require minimum acceptable visual acuity. In Iran, the accepted routine test to take driving license is Snellen vision chart, which is not adequate for visual acuity determination in real and natural environment. It seems that introducing a more sensitive and specific screening t...

Gesture and motion recognition are needed for a variety of applications. The use of human hand motions as a natural interface tool has motivated researchers to conduct research in the modeling, analysis and recognition of various hand movements. In particular, human-computer intelligent interaction has been a focus of research in vision-based gesture recognition. In this work, we introduce a 3-...
