The natural continuum of visual processing from signal analysis to cognition inspires the search for extensions to current models to include some higher-level structural processing. This paper continues the authors’ study regarding the role of visual structure in cognition, where two representations of a natural image are considered: signal-based and structurally based. Structural representatio...

The increase in the numbers of both public and private higher learning institutions (HLI) in Malaysia has resulted in the industry becoming relatively very competitive. The situation calls for HLIs to focus on establishing a strong corporate image and providing student satisfaction to secure their loyalty. Delivering quality services would lead to student satisfaction and loyalty. This study re...

Image quality assessment (IQA) is a crucial technique in perceptual image/video coding, because it is not only a ruler for performance evaluation of coding algorithms but also a metric for ratio-distortion optimization in coding. In this paper, inspired by the fact that distortions of both global and local information influence the perceptual image quality, we propose a novel IQA method that in...

The structural similarity image quality paradigm is based on the assumption that the human visual system is highly adapted for extracting structural information from the scene, and therefore a measure of structural similarity can provide a good approximation to perceived image quality. This paper proposes a multi-scale structural similarity method, which supplies more flexibility than previous ...

This paper proposes a joint rate control scheme for multiple video sequences coding based on H.264/AVC standard that produces uniform picture quality. Structural Similarly Information (SSIM), is assessed as a coding complexity of a video program measure regarding its perceptual quality. Initial results are presented and discussed.

We construct metrics from the geodesics of the Structural Similarity index, an image quality assessment measure. An analytical solution is given for the simple case of zero stability constants, and the general solution involving the numerical solution of a nonlinear equation is also found. © 2012 Elsevier Ltd.

Effective IT governance will ensure alignment between IT and business goals. Organizations with ineffective IT governance will suffer due to poor performance of IT resources such as inaccurate information quality, inefficient operating costs, runaway IT project and even the demise of its IT department. This study seeks to examine empirically the individual IT governance mechanisms that influenc...

Purpose – Now-a-days, logistics research focuses on the ability of logistics to deliver a quality service and generate greater satisfaction with the delivered service. Therefore, the aim of this work is to analyze the quality, satisfaction, and loyalty sequence in the logistic service delivery context, with the purpose of considering the role of information and communication technologies (ICT) ...

This paper develops a theoretical framework to examine the relationship between e-tail quality dimensions, customer satisfaction and loyalty. Data from a survey of 415 online consumers were used to test the research model. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted to demonstrate the reliability and validity of the measurement model, and the Structur...

This study utilized the Information Systems Success (ISS) model in examining e-learning systems success. The study was built on the premise that system quality (SQ) and information quality (IQ) influence system use and user satisfaction, which in turn impact system success. A structural equation model (SEM), using LISREL, was used to test the measurement and structural models using a convenienc...
