Purpose To compare the results of corneal evaluation, either total thickness and opacity depth by both technologies AS- OCT Scheimpflug imaging Sirius placido topography. Methods sixty-eight eyes sixty- eight consecutive patients with opacities were examined AS-OCT imaging. Corneal measured compared determining interchangeability using Bland–Altman plotting. Results Total was (470.32±62.10) (46...

with the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. tracking people as they move through a camera network with non-overlapping field...

technology advancement improves the way we interact with computer systems. keyboard, mouse, and touchpad provide an easier and more natural way of interaction with a computer system. nowadays, by introducing low cost and high performance depth cameras like kinect and xtion, new opportunities are available for creating even more natural interfaces. in this paper, a new model was demonstrated for...

nowadays, the subject of vision metrology network design is local enhancement of the existing network. in the other words, it has changed from first to third order design concept. to improve the network, locally, some new camera stations should be added to the network in drawback areas. the accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...

This case series examines the magnitude and regional variation in scleral lens–induced corneal edema postradial keratotomy (RK) eyes. Scheimpflug imaging was used to measure thickness across central 6 mm before after lens wear nine post-RK eyes (median age 64 years). Variations were examined as a function of distance from center (six 0.5-mm annuli) 0° 360°. The median 2.19% (interquartile range...

Light scatter from the central human cornea was measured in 60 eyes of 60 patients using computerised image analysis of Scheimpflug slit image photographs. There was no correlation between the amount of scatter and the age of the patients (correlation 0.035, p = 0.79). In addition it was found that light was scattered more at the anterior and at the posterior surfaces of the cornea than from th...
