The present study considers a fuzzy natural color system (NCS) in which triangular pyramid membership functions are constructed on the NCS color triangle. This system can process a fuzzy input to an NCS and output a center of gravity of three weights associated with respective grades. Triangular membership functions are applied to the hue angle, and triangular pyramid membership functions are a...

Choosing clothes, food recognition and traffic signal analysis are major challenges for visually impaired persons. The existing automatic clothing pattern recognition is also a challenging research problem due to rotation, scaling, illumination, and especially large intra class pattern variations. This project, a camera based assistive framework is proposed to help blind persons for identificat...

Consider natural numbers {1, · · · , n} colored in three colors. We prove that if each color appears on at least (n + 4)/6 numbers then there is a three-term arithmetic progression whose elements are colored in distinct colors. This variation on the theme of Van der Waerden’s theorem proves the conjecture of Jungić et al.

Both folklore and theory imply that naturally occurring rainbows display a wide range of nearly pure colors. However, digital image analysis of color slides shows that the natural rainbow's colors are not especially pure and that the bow's background causes much of this desaturation.

in april, 2013, a suzhou hospital reported a nitrite intoxication patient in coma as well as 2 family members with the similar symptom 5 days ahead. we investigated the event to identify the cause, source and possible pollution ways of the contamination.we defined case as any person living in yshy community who has cyanosis and with at least one of the following symptoms: dizziness, headache, f...
