Remote sensing images are widely used in object detection and tracking, military security, other computer vision tasks. However, remote often degraded by suspended aerosol the air, especially under poor weather conditions, such as fog, haze, mist. The quality of directly affect normal operations systems. As such, haze removal is a crucial indispensable pre-processing step image processing. Addi...

Indonesia’s fire and haze problem is reviewed, and a model quantifying the relationship between drought and haze from biomass burning in western Indonesia is presented. Visibility observations from weather stations in Sumatra and Kalimantan were used as a haze indicator. The Drought Code component of the Canadian Forest Fire Weather Index System was used as a drought indicator. Using meteorolog...

A regional haze episode occurred in the Beijing, Tianjin and Hebei province (BTH) area in the North China Plain (NCP) from 16 to 19 January 2010. Data were collected and analyzed during the time frame of 14 through 23 January 2010 to include the haze event. The increase of secondary inorganic pollutants (SO 4 , NO − 3 , NH + 4 ) in PM2.5 was observed simultaneously at four sites, especially in ...

This paper addresses the problem of qualitative spatial reasoning and presents eecient algorithms to deal it. We assume a representation which views space as a totality of objects surrounded by a haze area and connected in terms of qualitative spatial relations. Statements relating objects in this represesentation are expressed in terms of haze-order constraints. Reasoning about haze-orders inv...

Image haze removal is essential in autonomous driving as the outdoor images captured during unfavorable weather conditions, such or snow, are affected by poor visibility. Much research has been done to overcome image degradation low contrast and faded color due haze. However, traditional model, a phenomenon neglected that several particles simultaneously involved light acquisition. To address t...

PURPOSE To compare the outcomes of bandage contact lens (BCL) removal on the fourth versus seventh post-operative day following photorefractive keratectomy (PRK). METHODS This study recruited eyes of patients who underwent PRK surgery. The patients were randomly assigned to 2 groups. In Group 1 BCL was removed on the 4th postoperative day, while in Group 2, BCL was removed on the 7th postoper...
