While contrast normalization is well known to occur in luminance vision between overlaid achromatic contrasts and in colour vision between overlaid colour contrasts, it is unknown whether it transfers ...
Prof Sei-ichi Tsujimura of the Nagoya City University and Prof Su-Ling Yeh of National Taiwan University and Kagoshima University, have discovered that our visual acuity (contrast sensitivity) can be ...
Previous work has shown that human vision performs spatial integration of luminance contrast energy, where signals are squared and summed (with internal noise) over area at detection threshold. We ...

It is often difficult for a driver to see a person walking on the side of the road at night—especially if the person is wearing dark colors. One of the factors causing this difficulty is a decrease in ...
An iPad<sup>®</sup> application has been developed that can help physicians screen for Parkinson's Disease, report researchers. Patients with Parkinson's disease (PD) often have difficulties with ...
The minimum level of black and white a person needs to detect a pattern on seeing is known as contrast sensitivity. Previous studies have shown that the optics in the eye and processing in the brain ...
Older adults with contrast sensitivity impairment are at greater risk for falls than those without vision problems, a new study found. Researchers from the University of Michigan at Ann Arbor and the ...
