Generally, image fusion methods are classified into three levels: pixel level (iconic), feature level (symbolic) and knowledge or decision level. In this paper we focus on iconic techniques for image fusion. Usually, image fusion techniques such as intensity-huesaturation (IHS) or Brovey are used to fuse high spatial resolution panchromatic and lower spatial resolution multispectral images that...

The fusion image of IKONOS optical data and COSMO-SkyMed SAR image is used as the classifier inputs for land cover classification under an object-oriented paradigm. Firstly, Frost filter is selected to reduce speckle noises of SAR image. Three popular methods, including IHS, PCA and wavelet transform, are applied to fuse high resolution optical and SAR images. Comparing with other fusion method...

A study using the spiral dynamics optimization algorithm to evaluate the human health effects of using computer-aided workstations on employees. We collected data for human health risk on employees at their workplaces, analyzed the data and proposed corrective measures applying our methodology. It includes a checklist with nine human health dimensions: work organization, displays, input devices...

Image fusion is an important tool in remote sensing, as many Earth observation satellites provide both high-resolution panchromatic and low-resolution multispectral images. To date, many image fusion techniques have been developed. However, the available algorithms can hardly produce a satisfactory fusion result for IKONOS and QuickBird images. Among the existing fusion algorithms, the IHS tech...

BACKGROUND The financial burden of cancers has profound effects and there is a clear need to explore the issue from different perspectives and for different population groups. This study aimed at investigating inpatient cancer care (ICC) burden in Anhui, a typical inland province of China. METHODS The study collected data through a household survey conducted during April to November, 2014 usi...

This paper is a description of our system developed for SemEval-2016 Task 9: Chinese Semantic Dependency Parsing. We have built a transition-based dependency parser with online reordering, which is not limited to a tree structure and can produce 99.7% of the necessary dependencies while maintaining linear algorithm complexity. To improve parsing quality we used additional techniques such as pre...

In this paper, a fusion method is proposed, which provides an integrated map of an urban area starting from co-registered optical (panchromatic and multispectral) and SAR images. Classical Intensity-Hue-Saturation (IHS) transform based methods, or Principal Component Substitution (PCS) approaches do not take into account the contextual spatial information, and do not exploit conveniently the co...

We derive equilibrium properties of participation in a large family of economic games that take place when players’ information is incomplete. The fact that participation is almost always costly introduces a crucial distinction between players and participants. The number of players is exogenous but the number, or distribution, of participants is part of equilibrium. We assume a quite general s...

BACKGROUND The prevalence of tobacco smoking in Germany is high (~27%). Monitoring of national patterns of smoking behaviour and data on the "real-world" effectiveness of cessation methods are needed to inform policies and develop campaigns aimed at reducing tobacco-related harm. In England, the Smoking Toolkit Study (STS) has been tracking such indicators since 2006, resulting in the adaptatio...

ancestors lived in North America before the European settlement. In the United States alone, there are more than 500 tribal organizations. In addition to their tribal affiliations, Native Americans are often distinguished by language and/or cultural groups, some of which extend across both the United States and Canada. Contemporary Native American populations live in urban areas and on reservat...
