Much research has been devoted in recent years to recognizing human action from video images. Most existing methods, however, take video of people from the outside making it difficult to understand behavioral intention. The First Person Vision approach has been proposed in response to this problem. In this approach, a device consisting of two cameras collectively called an “inside-out camera” i...

In this paper, we have analyzed the performance of WDM Ethernet Passive Optical Network (EPON) with Radio over Fiber (RoF) optical link with the use of Dispersion compensating fiber at the transmission section. Performance of the system is improved with the use of DCF. The results are compared with and without DCF. The BER, Q factor and eye diagrams have been used for evaluating the performance...

PURPOSE To determine if the use of pigments or adding polyvinyl pyrrolidone during the fabrication of 1-DAY ACUVUE DEFINE (AD) brand contact lenses impacts open-eye corneal swelling compared with no lens wear (NLW). METHODS A partial double-masked, randomized, bilateral crossover study was conducted in 24 Asian subjects using AD, 1-DAY ACUVUE DEFINE with Lacreon (ADL), NLW, and a control lens...

Conventional optical systems usually provide best image quality on axis, while showing unavoidable gradual decrease in image quality towards the periphery of the field. The optical system of the human eye is not an exception. Within a limiting boundary the image quality can be considered invariant with field angle, and this region is known as the isoplanatic patch. We investigate the isoplanati...

PURPOSE To compare the prevalence of refractive errors, amblyopia, and strabismus between hearing-impaired and normal children (7-22 years old) in Mashhad. METHODS In this cross-sectional study, cases were selected from hearing-impaired children in Mashhad. The control group consisted of children with no hearing problem. The sampling was done utilizing the cluster sampling method. All of the ...

Microaneurysms physical weakening of the capillary walls which predisposes them to leakages. Hard exudates precipitates of lipoproteins/other proteins leaking from retinal blood vessels. Haemorrhages rupture of weakened capillaries, appearing as small dots/larger blots or 'flame' haemorrhages that track along nerve-fibre bundles in superficial retinal layers (the haemorrhage arises from larger ...
