Blind and visually disabled persons use special software environments – such as Windows-Eyes, JAWS, screen-readers, text-to-speech programs – to access personal computers. These software solutions may offer sound samples for a better orientation. Besides speech, there are auditory icons, earcons or spearcons as possible extension of visual information. Finding the optimal mapping between (visua...

Blind people can be defined as those who are unable to see objects or pictures around them with their eyes. This inability becomes an issue for when dealing images in front of them. These problems lead the novelty this study that is recognize blind CNN algorithm. Dogs and cats were used study. object recognitions Deep Learning, a relatively new science field machine learning. learning works lik...

Two sources of data (a blind register and the records of a glaucoma clinic) were used to study the age, sex, and ethnic characteristics of sufferers of glaucomatous blindness in the Negev region of Israel. Glaucoma was found to be the cause of blindness relatively infrequently (10% of eyes) among the registered blind population. The rate of blindness from glaucoma in the population was 0.38/100...

The human natural blind spot is usually filled in based on the contextual information. When two sufficiently different images are presented to the two eyes, observers typically perceive an alternation between the two images (binocular rivalry). Both the filling-in process and binocular rivalry have been the subject of considerable research. This study investigates whether filled information in ...

the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...

OBJECTIVE Studies indicate that the change from closed to open eyes in a resting condition results in an increase in skin conductance level (SCL) and a global decrease in EEG alpha activity, both indicative of increased arousal. Other studies show that ingestion of caffeine also produces SCL increase and alpha reduction. This study investigated the additivity of the effects of these two indepen...

BACKGROUND Cataract is the leading cause of blindness in children in east Africa. The results of surgery are poor, partly because of inadequate correction of aphakia. METHODS A retrospective survey of 118 eyes in 71 children with bilateral cataract. All eyes had implantation of an IOL at the time of cataract surgery. The average age at surgery was 3.5 years. 28 patients(39%) were less than 2 ...

BACKGROUND: In developing countries congenital cataract has become an important cause of treatable blindness in childhood. However, difficulty in correcting aphakia is one of the reasons for poor visual outcome. OBJECTIVE: To determine the visual outcome after extra capsular cataract extraction and intra ocular lens implant and factors militating against good visual outcome in children. METHODS...

BACKGROUND This study addresses the prevalence and clinical presentation of patients with primary open angle glaucoma (POAG) in the greater Accra metropolitan area. METHODS This is a retrospective case series of 455 patients (813 eyes) at the Emmanuel Eye Clinic. Patients were diagnosed from May 2008 to Nov 2011. The definition of POAG conformed to the International Society of Geographical an...

In addition to routine medications topical indomethacin was applied to one group of 112 eyes and an appropriate placebo was applied to another group of 106 eyes that underwent intracapsular cataract extraction. The investigation was conducted in a prospective double blind fashion over a long period of time in order to demonstrate the effects of indomethacin in preventing the development of cyst...
