Two-step image segmentation algorithm is proposed, which is based on region coherency for the segmentation of color image. The first step is the watershed segmentation, and the next one is the region merging using artificial neural networks. Spatially homogeneous regions are obtained by the first step, but the regions are oversegmented. The second step merges the oversegmented regions. The prop...
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
in iran we already use laminate tubes only in cosmetics industry. laminate tube manufacturers via using the most modern technology of the world, faced with the laminate tube market being saturated in cosmetics industry for packaging the cosmetic creams and toothpaste. but considering the great food market and therefore laminate tube features such as beautiful packaging, ease of use for the fina...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
Ni-Fe-Cr-Al alloy has been subjected to 2 hours aging treatment between 600-900°C, which influenced the mechanical properties and resulted in discontinuous precipitation at grain boundaries. In this study, SEM, TEM STEM-EDXS were applied explore relationship occurring boundary phenomena behavior. Within zone, three different phases recognized, namely ? solid solution with lamellar M23C6 carbide...
HEIGHTS WITH POLINSAR DATA Lulu Tan , Ruliang Yang, Weidong Yu 1 Institute of electronics, Chinese Academy of Sciences, China; 2 Graduate University of Chinese Academy of Sciences, China. Email: [email protected]; [email protected]; Polarimetric synthetic aperture radar interferometry (PolInSAR) is a perspective remote sensing technique that has been intensively used for extracting forest ...
In this paper we present a technique for the interactive control and display of static and dynamic 3D datasets. We describe novel ways of tri-linear interpolation and gradient estimation for a real-time volume rendering system, using coherency between rays. We show simulation results that compare the proposed methods to traditional algorithms and present them in the context of Cube-3, a special...
Dynamic data is data which varies rapidly and unpredictably. This kind of data is generally used in on-line decision making and hence needs to be delivered to its users comforming to certain time or value based applicationspecific requirements. The main issue in the dissemination of dynamic web data such as stock prices, sports scores or weather data is the maintenance of temporal coherency wit...
