This paper introduces an energy-based model (EBM) for region labeling that takes advantage of both context and semantics present in segmented images.The proposed method refines the output of multiclass classification methods that are based on the one-vs-all (OVA) formulation. Intuitively, the EBM maximizes the semantic cohesion among labels assigned to neighboring regions; that is, a tradeoff b...
A new online region-based active contour model (ORACM) is proposed in this paper. The classical geode-sic active contour (GAC) model has only local segmentation property, although the Chan–Vese (C–V) model possesses global. An up-to-date active contour model (ACM with SBGFRLS) proposed in Zhang, Zhang, Song, and Zhou (2010) both has the properties of global/local segmentation and incorporates t...
in this research using gis effect of land management and soil criteria with eight indicators to study the sensitivity to the desert lands of the region of sistan jazinak creation is evaluated. vote based on the model parameters wilderness - the latest creation esas evaluation method wilderness creation and in most european countries and the middle east is used, took place. using the above metho...
In this research, based on the observed data of Class A pan evaporation and application of non-linear regression (NLR), artificial neural network (ANN), neuro-fuzzy (NF) as well as Stephens-Stewart (SS) methods daily evaporation of Kerman region was evaluated. In the cases of NLR, ANN and NF methods, the input variables were air temperature (T), air pressure, relative humidity (RH), solar radia...
Model generation has emergcd as a key task in engineering design and analysis. Al research in this area has focusedon model based reasoning emphasising qualitative models in attempting to automate this process. In this paper, we propose that this work on the use of model based reasoning in model generation would benefit from the inclusion of case-based reasoning (CBR) techniques. We argue that ...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
Topographic factor is an important factor of computer models of USLE family due to the high sensitivity of model results to its variation and complicated effects of topography on soil erosion. Moore and Wilson (1992) have introduced a well-known method to compute LS factor of RUSLE model using digital elevation model (DEM).The objective of this study was to determine the proper cell size of DEM...
روابط بین مراحل زندگی (لاروی، گذر و بلوغ) شانه دار mnemiopsis leidyi و شاخصه های فیزیکوشیمیایی و زیستی با استفاده از مدل های مختلف بر اساس تغییرات زمانی (ماه) و مکانی (ترانسکت، ایستگاه و لایه) در امتداد سواحل مازندران طی سال 1391 ارزیابی شد. به منظور بالا بردن عملکرد مدل ها، از گونه های غالب پلانکتونی در هر فصل (90% تراکم کل) برای مدل سازی استفاده گردید. برای درک بهتر از وضعیت اکولوژیکی شانه ...
abstract the current study sets out 1) to investigate the strategic needs of iranian efl learners in reading literary and non-literary texts; 2) to shed some light on the differences between reading literary and non-literary texts; and 3) to specify the differences in the interaction of participants with texts while reading two literary subgenres ( i.e., short story and literary essays). to ...
