In this paper, we propose a novel and simple fast block-matching algorithm (BMA), called adaptive rood pattern search (ARPS), which consists of two sequential search stages: 1) initial search and 2) refined local search. For each macroblock (MB), the initial search is performed only once at the beginning in order to find a good starting point for the follow-up refined local search. By doing so,...

the growing population and increasing socio-economic necessitiescreates a pressure on land use/land cover. nowadays, land use change detection using remote sensing data provides quantitative and timely information for management and evaluation of natural resources. this study investigates the land use changes in part of hableh rood watershed of iran using landsat 7 and 8 (sensor etm+ and oli) i...

The adaptive rood pattern search (ARPS) algorithm proposed by Nie and Ma has shown two to three times of search speed-up improvement over that of diamond search (DS) based on the MPEG4 Verification Model encoding platform. In this paper, first we have shown that the distribution of motion vectors bears a rood shape. An improved ARPS algorithm, called ARPS-3 or unequalarm ARPS, is then proposed ...

hazelnut is grown in limited areas of iran with high rainfall and high relative humidity. new cultivars and rootstocks that are tolerant of drought and low humidity are needed to expand hazelnut cultivation. to this end, seeds of 14 local corylus avellana l. genotypes (a1, a2, gerche, gerde eshkevarat, gerde shok, mahalli karaj, nakhon rood, navan1, navan7, navan9, navan10, pashmineh, shirvani ...

previous reports on intestinal parasite from isfahan area revealed wide distribution of intestinal parasitic infections in the area. since all studied areas were situated in the banks of zayandeh rood river with lot of trees and a humid soil, it was suggested, for comparison, to undertake a similar study in a village with comparatively dry and district climate. the village segzi (42 kilometer, ...

social media has quickly become an essential marketing and communication tool for private, public and non-governmental entities across the world to promote their organizational mission, daily events and publications. many citizens use social media to post or share real time photos on a variety of environmental issues such as pollution or littering, forest fires, reported chemical spills in wate...

one of the characteristics in iranian model of desertification potential assessment (imdpa) is vegetation. sincevegetation is very important factor in the degradation of land, so some indices were determined for this item in order toevaluate desertification potential of arid, semi arid and arid sub humid areas of iran. the indices included vegetationcondition, exploit and revegetation. to calib...
