In this paper, we propose a new fast dehazing method from single image based on filtering. The basic idea is to compute an accurate atmosphere veil that is not only smoother, but also respect with depth information of the underlying image. We firstly obtain an initial atmosphere scattering light through median filtering, then refine it by guided joint bilateral filtering to generate a new atmos...

Skin lesions are often comprised of various colours. The presence of multiple colours with an irregular distribution can signal malignancy. Among common colours under dermoscopy, blue-grey (blue-white veil) is a strong indicator of malignant melanoma. Since it is not always easy to visually identify and recognize this feature, a computerised automatic colour analysis method can provide the clin...

“Dr. D,” a 32-year-old female general practitioner, presented to a psychiatric referral clinic with a history of repetitive hair pulling since age 14. Recently the hair pulling had escalated, and it now occupied 2–3 hours per day, usually during the evening when Dr. D was relaxing. Despite imaginative efforts to conceal her missing hair and eyebrows, Dr. D felt that she was “fighting a losing b...

Harris argues that if QALYs are used only 50% of the population will be eligible for survival, whereas if random methods of allocation are used 100% will be eligible. We argue that this involves an equivocation in the use of "eligible", and provides no support for the random method. There is no advantage in having a 100% chance of being "eligible" for survival behind a veil of ignorance if you ...

Toxicity of some legally sold alcoholic beverages has contributed to enhanced mortality in Russia since 1990. Widespread drunkenness during the early 1990s facilitated privatization of economy: workers and some intelligentsia did not oppose privatizations because of drunkenness and involvement in illegal activities. Apparently, alcohol consumption and heavy binge drinking have been decreasing i...

Grogger and Ridgeway (2006) develop a feasible test for racial profiling "behind a veil of darkness" that exploits the exogenous variability in the visibility of driver race caused by the daylight savings time shift. The idea is that police are less able to use race as a criteria in traffic stops when it is dark, so differences in stop rates for African-Americans between dark and light (while c...

As recently as 1937, Horace C. Pitkin in an article in the "Journal of Bone and Joint Surgery" wrote: "Manipulative surgery is a therapeutic waif of lowly origin whose infancy and childhood have been shielded from the light of reason by a congenital veil of empiricism and quackery." Yet in spite of such hereditary handicaps, it continues to thrive wonderfully; and perhaps in no better field tha...
