With the development of 3D devices such as TV, monitors, and mobile phones, 3D display can support multiple viewpoints in the user's terminal. For these applications, higher coding efficiency for stored or transmitted data is significant, since the number of views has been increased with the technical development of 3D display. To adapt the coder to 2D and diverse views devices, it is important...

Seemingly complex tasks like visual search can be analyzed using a cognition-free, bottom-up framework. We sought to reveal strategies used by observers in visual search tasks using accurate eye tracking and image analysis at point of gaze. Observers were instructed to search for simple geometric targets embedded in 1/f noise. By analyzing the stimulus at the point of gaze using the classificat...

Objective. To determine maternal morbidity in women with placenta previa managed with prediction of morbidly adherent placenta (MAP) by ultrasonography. Methods. A retrospective cohort study was undertaken comprising forty-one women who had placenta previa with or without risk factors for MAP. Women who had all three findings (bladder line interruption, placental lacunae, and absence of the ret...

the measurement of wheat crop yield in large areas is time consuming and requires high expenses. one way to save time and cost, using geostatistical methods for mapping crop yield. in this research principle component analysis were used for identifying variables that have correlation with each other, and kriging and cokriging were used to map crop yield prediction. fourty six samples were used ...

landsat data for 1992, 2000, and 2013 land use changes for ekbatan dam watershed was simulated through ca-markov” model. two classification methods were initially used, viz. the maximum likelihood (mal) and support vector machine (svm). although both methods showed high overall accuracy and kappa coefficient, visually mal failed in separating land uses, particularly built up and dry lands.there...

Helpful online product reviews, which include massive information, have large impacts on customers? purchasing decisions. In most of e-commerce platforms, the helpfulness reviews are decided by votes from other customers. Making full use these with has enormous commercial value, especially in recommendation. It drives researchers to study technologies about how evaluate review automatically. Al...
