We propose a system for estimating a user’s view direction with its location of a captured image by retrieving its corresponding region from panoramas in a database. In our database, 104 panoramas captured within a local area are stored. For retrieving a user’s location, the query image captured by the user’s planarprojection camera is compared with all the panoramas in the database. SURF is us...

The central goal of this project is a deeper understanding of the dynamic adjustment of mobile sandy sediments to fluid forcing in and near the surf zone at small (1cm to 10m) and intermediate (10m to 100m) horizontal scales. The effort is motivated by the dual need to develop more realistic models of fluid-sediment interactions in the nearshore zone, and for suitable in situ measurement techni...

Recent improvements in web standards and technologies enable the attackers to hide and obfuscate infectious codes with new methods and thus escaping the security filters. In this paper, we study the application of machine learning techniques in detecting malicious web pages. In order to detect malicious web pages, we propose and analyze a novel set of features including HTML, JavaScript (jQuery...

land cover classification is one of the most important applications of polarimetric radar images, especially in urban areas. there are numerous features that can be extracted from these images for the use of their high potential, hence feature selection plays an important role in polsar image classification. in this study, three main steps are used to improve the classification: 1) feature extr...

This study examined whether the number of shared topic-vehicle significant features affects speakers’ preference for use metaphorical rather than literal expressions. Across five experiments, participants were asked to choose one expression that best paraphrased a given sentence from list options. The results Experiments 1 and 5 showed participants’ choice increased with greater numbers in sent...
