In the paper a probabilistic approach to quality assessment of image processing algorithms is proposed. Presented scalar measure can be used for any colour space and gives very similar results regardless on the image content. It can be an interesting supplement to existing image quality metrics in applications where the details of the processing algorithm are known. Its good correlation with su...

Despite its relative robustness, subjective video quality evaluation is a time-consuming and costly process. Alternatives are required therefore to simplify visual quality estimation, particularly in the case of new video formats. This paper presents an analysis of full reference quality metrics focused on Ultra High Definition sequences, encoded with H.265/High Efficiency Video Coding. After e...

Web-based information systems are increasingly being used for decision support applications. However few empirical studies have been conducted on web-based decision support systems (DSS). This experimental research endeavors to understand factors that impact decision-making satisfaction in web based decision support systems. Using structural equation modeling approach, the analysis reveals that...

Absolute Mean Brightness Error (AMBE) and entropy are two popular Image Quality Analyzer (IQA) metrics used for assessment of Histogram Equalization (HE)-based contrast enhancement methods. However, recent study shows that they have poor correlation with Human Visual Perception (HVP); Pearson Correlation Coefficient (PCC)<0.4. This paper, proposed a new IQA which takes into account important pr...

In recent years, revenue management has become an important competitive strategy in the hotel, and the level of hotel performance directly reflects the effectiveness of the application of revenue management. But so far, academic research about hotel revenue management performance influencing mechanism and evaluation is still extremely limited. Based on fully retrieving the relevant literature, ...

Sensitive equipment and non-linear loads are now more common in both the industrial/commercial sectors and the domestic environment. Because of this a heightened awareness of power quality is developing among electricity users. Therefore, power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Continuous variation of single-phase loads ...

Semi-structured data are prevalent on the web, with formats such as XML and JSON soaring in popularity due to their generality, flexibility and easy customization. However, these same features make semi-structured data prone to a range of data quality errors, from errors in content to errors in structure. While the former has been well studied, not much attention has been paid to structural err...

This paper explores the online customer experience (OCE) in relation to a utilitarian search for government provided business support services. The aim of this research is to understand the variables that can influence customers searching for business support services online and to explore the potential role of online customer support via social interaction during a customer’s online experience...

DeLone and McLean's (1992) comprehensive review of different information system success measures concludes with a model of interrelationships between six IS Success constructs. This paper critically examines the meaning of four of these constructs and the evidence of relationships between them. It then provides results from empirical tests of these relationships. Tests are conducted using both ...

With the global economic crisis and industrial restructuring, the unemployed are suffering from job loss-related stress and loss of income, which is believed to impair their mental and physical health, while coping and self-efficacy could combat the adverse effects of unemployment on health. Thus, this study aims to describe quality of life (QOL) among unemployed Chinese people and explore the ...
