The aim of this study is investigates the effects of different patches shrubs on the soil surface indicators in Gub Gugeh rangelands, in Golestan Province. The sampling was taken along transects of 50 meters, which are 10 meters away from each other. Via LFA models, three factors of stability, infiltration and nutrient cycling using 11 indicators of surface soil in patch and inter-patch were me...

This study was conducted to evaluate the effect of copper extraction on the structure and function of rangelands ecosystem around the mine area in Dareh Zereshk, Yazd province, Iran. Three study sites were considered at the specified intervals of the mine (0-200, 200-500 and 500-1000m). This research was conducted from 2012 to 2013. In each location, three linear transects with a length of 50 m...

rangeland ecosystem contains various patches with different functions. structural and functional characteristics of rangeland patches are changed by management practices and can be used to interpret management effects. the structural and functional characteristics of fertilized patches in two rangeland ecosystems of ghareh ghir and maraveh tapeh were measured and analyzed in this study. a group...

In the current study, conservation strategies were employed for the spatial analysis of forest fragmentation and field assessment approaches in a forest landscape of Central Zagros, in the western part of Isfahan province, Iran. Vegetation and soil properties were accordingly studied in 15 forest sites with various densities including dense, semi-sparse and sparse-forests with 839.2 km2. In the...

Processing natural scenes requires the visual system to integrate local features into global object descriptions. To achieve coherent representations, the human brain uses statistical dependencies to guide weighting of local feature conjunctions. Pairwise interactions among feature detectors in early visual areas may form the early substrate of these local feature bindings. To investigate local...

In this paper, we propose a full-reference (FR) image quality assessment (IQA) scheme, which evaluates image fidelity from two aspects: the inter-patch similarity and the intra-patch similarity. The scheme is performed in a patch-wise fashion so that a quality map can be obtained. On one hand, we investigate the disparity between one image patch and its adjacent ones. This disparity is visually...

Introduction: As one of the most serious environmental challenges of Iran during the recent decade, the phenomenon of fine dust has occurred due to improper and excessive ecologic use of rangeland ecosystems, drought, and mismanagement of water resources. Knowing this phenomenon and being aware of the required strategies to fight against it play an essential role in reducing the number of dust ...

Inter prediction is an important component for video coding which exploits the temporal correlation between frames and significantly reduces the redundancy in video sequences. In this paper, we propose a predictive patch matching for inter prediction based on template matching prediction. Besides the surrounding reconstructed pixels which form the template in template matching prediction, our p...
