The time course for the development of the temporal contrast sensitivity function in humans is uncertain. Some studies indicate that temporal contrast sensitivity is immature in infants. However, earlier work suggests that critical flicker fusion is adult-like by 2 months. We traced the development of temporal contrast sensitivity to uniform field flicker in 2-, 3- and 4-month-old infants using...

A method of video flame detection based on multi-feature fusion is presented in this paper. Physical characteristics of flame, including color clues, flame movement and flame flicker are incorporated into the scheme to detect fires in color video frames. Firstly, mean filtering was used to smooth the video frames and a flame color filtering algorithm was adopted to extract flame candidate regio...

Extensive retinal vascular disease was noted in three patients from two families with Favre-Goldmann syndrome. In addition to classical features they had pronounced leakage from some retinal vessels. Vessels were either opaque ('sclerotic') or non-perfused. Cystoid macular oedema was a contributing cause of decreased vision. Two of the three patients showed a discrepancy on electroretinography ...

Background: Human brain performance and arousal are still challenging critical, especially in environments such as power plants. Since different emotions common daily work life have inevitable effects on cognitive performance, it is important to evaluate whether emotional interventions can alter arousal. Poor control room operators (CROs) lead mental fatigue affect their emotion regulation. To ...

The critical flicker fusion frequency (CFF) is the frequency at which a flickering stimulus is perceived to be steady, with higher values suggesting greater perceptual accuracy. The CFF was measured in two age-matched groups of healthy male volunteers whose ages ranged from 25 to 39 years, with 18 subjects in each group. After baseline assessments one group (yoga group) received yoga training, ...
