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...

Digital photogrammetry was performed on stereophotographs of the optic nerve head of a modified Zeiss model eye in which optic cups of varying depths could be simulated. Experiments were undertaken to determine the impact of both photographic and ocular variables on the photogrammetric measurements of cup depth. The photogrammetric procedure tolerates refocusing, repositioning, and realignment ...

Eye movement is a basic human behavior that offers a valuable means to explore human cognitive processes. This article introduces two modeling studies of eye movement. First, random menu search was modeled using a queueing network approach and second, a reinforcement learning algorithm was used to generate various eye movement patterns. Random menu search is a task component involved in many hu...

purpose: to evaluate bacterial and fungal contamination of donor corneas before and after decontamination at eye bank of i.r. of iran based on cultures. methods: this descriptive study was performed on 131 donor eyes (whole globe or cut cornea) used for corneal transplantation at labbafinejad hospital during a 6-month period. microbiologic culture was performed at three stages: before enucleati...

We develop a statistical model of saccadic eye movements during reading of isolated sentences. The model is focused on representing individual differences between readers and supports the inference of the most likely reader for a novel set of eye movement patterns. We empirically study the model for biometric reader identification using eye-tracking data collected from 20 individuals and observ...

introduction: human eye is a sensitive part of human body with no direct protection and due to its lack of protection against the external heat waves, studying the temperature distribution of heat waves on the human eye is of utmost importance. various lasers are widely used in medical applications such as eye surgeries. the most significant issue in the eye surgeries with laser is estimation o...

Eye plays an important role in collecting information of face characteristics. The eye region includes information of gesture, identity, gender and etc. It can be used in many applications such as gesture understanding, fatigue driving, eye blink detecting, disabled-helping domain, psychology domain, human-machine interaction, face recognition in video, and so on. Eye tracking is the focus prob...

A lot of researches have investigated the effects of topical cyclosporine A on the eye surface layers’ diseases. By now the main limitation in cyclosporine application is the low permeation of the drug into the posterior segments of the eye. The aim of present study was to formulate high permeable dosage form can be beneficial in the topical treatment of the uveitis. To reach higher corneal dru...
