In the present work sedative and hypnotic effects of aqueous extract of Aloe vera in rats have been investigated. In order to evaluate the overall hypnotic effects of the Aloe vera extract, open field and loss of righting reflex tests were primarily used. The sedative and hypnotic effects of the extract were then confirmed by detection of remarkable raise in the total sleeping time through anal...

In this thesis we present a system to extract the eye motion from a video stream containing a human face and applying this eye motion into a virtual character. By the notation eye motion estimation, we mean the information which describes the location of the eyes in each frame of the video stream. Applying this eye motion estimation into a virtual character, we achieve that the virtual face mov...

− Autostereoscopic display systems can provide users a natural 3-D visualization environment by projecting stereo video onto the user's eyes. Eye position localization is a central module in this kind of display system when users are allowed to move freely. This paper presents robust 3-D eye tracking techniques that can provide accurate eye positions in real time. Technical batteries comprise: ...

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 and aims: epstein-barr (ebv) virus infection is very common in the population. virus belongs to the family herpesviridae, whose representatives are characterized by the ability to cause the human body latent persistent infections. the goal of study is to assess ebv infection frequency and pcr method in the choice of ebv in inflammatory eye disease, comparing with ebv presence in eye ...

Eye state recognition is one of the main stages of many image processing systems such as driver drowsiness detection system and closed-eye photo correction. Driver drowsiness is one of the main causes in the road accidents around the world. In these circumstances, a fast and accurate driver drowsiness detection system can prevent these accidents. In this article, we proposed a fast algorithm fo...

Real-time eye detection is important formanyHCI applications, including eye-gaze tracking, autostereoscopic displays, video conferencing, face detection, and recognition.Current commercial and research systems use software implementation and require a dedicated computer for the image-processing task—a large, expensive, and complicated-to-use solution. In order to make eye-gaze tracking ubiquito...

In this paper, the generalized projection function (GPF) is defined. Both the integral projection function (IPF) and the variance projection function (VPF) can be viewed as special cases of GPF. Another special case of GPF, i.e. the hybrid projection function (HPF), is developed through experimentally determining the optimal parameters of GPF. Experiments on three face databases show that IPF, ...

PURPOSE To examine associations between corneal mechanical thresholds and metrics of dry eye. METHODS This was a cross-sectional study of individuals seen in the Miami Veterans Affairs eye clinic. The evaluation consisted of questionnaires regarding dry eye symptoms and ocular pain, corneal mechanical detection and pain thresholds, and a comprehensive ocular surface examination. The main outc...
