Eyes are the most salient and stable features in the human face, and hence automatic extraction or detection of eyes is often considered as the most important step in many applications, such as face identification and recognition. This paper presents a method for eye detection of still grayscale images. The method is based on two facts: eye regions exhibit unpredictable local intensity, therefo...

Method for psychological status monitoring with line of sight vector changes (human eye movement) detected with wearing glass is proposed. Succored eye movement should be an indicator of humans’ psychological status. Probability of succored eye movement, therefore, is measured. Through experiments with simple and complicated documents, relation between psychological status measured with eeg sig...

Event detection is a challenging stage in eye movement data analysis. A major drawback of current event detection methods is that parameters have to be adjusted based on eye movement data quality. Here we show that a fully automated classification of raw gaze samples as belonging to fixations, saccades, or other oculomotor events can be achieved using a machine-learning approach. Any already ma...

Red-eye and flash-eye defects in still photography continue to cause problems for digital imaging devices. New variants of flash-eye defects have appeared as cameras and cameras sub-systems get smaller in size. This paper reviews a wide range of the more recently patented techniques that have been applied to solve various problems associated with red and non-red flash-eye, particularly solution...

results males (8,593 patients) were more likely to have eye trauma than females (1,262). the mean age for the outpatient cases was 20.3 ± 16.39 years and for the inpatient cases it was 22.7 ± 18.95 years. the workplace was the most common site for trauma and the cornea was the most reported anatomically injured site. for those patients who had not used safety and protection equipment, 93.1% wer...

purpose: dry eye syndrome is a multifactorial disorder of the tear film and ocular surface that results in eye discomfort, visual disturbance, and often ocular surface damage. studies suggest that the prevalence of clinically diagnosed dry eye syndrome (des) is 0.4%. to 0.5%, which is highest among women and the elderly. the burden of des can be substantial, affecting visual function, daily act...

Eye detection is a complex issue applied in several applications, such as human gaze estimation, Human-Robot interaction and driver’s aid framework for automatic drowsiness detection. This paper presents an algorithm that detects the human eye in still gray-scale images. The proposed scheme is based on learning statistical appearance model, which implies; the extraction of features and their cl...

Accurate detection of the eye state (i.e., open or closed) of animals during electrophysiological recordings is often crucial for analyzing physiological data. This requires a system which is reliable, and preferably noninvasive and inexpensive. Here we present such a tool incorporating a standard digital camera and a semi-automatic eye state detection (ESD) algorithm that can be used easily in...

Mobile devices have been widely used not only as a communication tool, but also a digital assistance to our daily life, which imposes high security concern on mobile devices. In this paper we present a natural and non-intrusive way to secure mobile devices, i.e. a complete and fully automated face verification system. It consists of three sub-systems: face detection, alignment and verification....

PURPOSE To report a case of varicella-zoster virus (VZV) keratitis with detection of VZV DNA in the tear fluid of not only the symptomatic eye but also the contralateral asymptomatic eye by polymerase chain reaction (PCR). METHODS This is a case report. A 63-year-old otherwise healthy woman presented with circular corneal ulcer and stromal opacity with infiltration accompanied by mild conjunc...
