One of the most important environmental challenges which exists in the Middle East and Iran in recent years is the phenomenon of dust. As regards the Western half of Iran is in proximity to large deserts and continually effects the country deserts dust and specially that western half and also the unpleasant effects that these dusts have on environment and people health; so the purpose of this s...
the images of muslims in media, literature and politics have been mostly black and white portrayals of a people alien to modernity, civilization, rationality and pluralism. since the end of the cold war and the onset of deadly terrorist attacks in different areas of the world, especially in the united states, these representations show a palpable difference: muslims are represented not only as ...
Abstract Contemporary studies of geographical space, including archaeological research, incorporate multiple spatial digital data. Such data provide an opportunity to extend research large areas, and objectify on the basis quantitative thus obtained gaining access hard-to-reach study area. Examples such are satellite images at various resolutions in a wide spectrum electromagnetic radiation (vi...
Image Enhancement is one of the most significant and challenging techniques in image research. The goal of image enhancement is to increase the visual appearance of an image, or to deliver an “enhanced transform representation for forthcoming automated image processing. Many images like medical images, satellite images, aerial images and even real life photos suffer from poor contrast and noise...
One of the most common natural phenomena occurring in mountainous regions of the world is landslide which causes critical damages and is considered as a natural disaster. Iran is a country which annually suffers from this disaster and its consequent damage of about 500 billion Rial. Over the last 15 years, an increasing number of researches have aimed to demonstrate the applicability of the im...
The feasibility to develop a rapid urban seismic damage detection procedure utilizing satellite radar imagery is investigated. In direct observation of city-wide building loss, remote sensing damage detection techniques have shown merits in rapid damage detection in urban areas. Remote sensing technology has the capability of extracting buildings in urban scenes. Comparing “before” and “after” ...
In this paper, the possibilities of using visual and textual information are investigated to improve the ranking of photos from Flickr about famous places. We have elaborated improved textual features based on standard ones and visual features e.g. face feature for measure the relative face area on the images. These heuristic features have been used for the solution in the MediaEval 2013 Retrie...
in recent years, acquiring information of remote sensing data, especially satellite data has excessively increased and several methods are presented in order to improve the quality of remote sensing studies in earth sciences. it is possible to manage many projects and provide different types of thematic maps in a short period of time, and a low cost by utilizing satellite data and gis method. r...
—Satellite remote sensing is being used operationally by Swedish authorities in applications involving, for example, change detection of clear felled areas, use of k-Nearest Neighbour estimates of forest parameters, and post-stratification (in combination with National Forest Inventory plots). For forest management planning of estates, aerial photointerpretation in combination with stand-wise f...
