This work concerns the developing of new perceptual metrics for 3D watermarking quality assessment. Any watermarking algorithm, to be effective, requires that the distortions it inevitably introduces into the watermarked media is imperceptible. This requirements is particularly severe for watermarking of 3D objects where the visual quality of the original model has to be preserved, i.e. the vis...

This article proposes a method that allows a value-based assessment of metadata quality and construction of a baseline quality model. The method is illustrated on a large-scale, aggregated collection of simple Dublin core metadata records. An analysis of the collection suggests that metadata providers and end users may have different value structures for the same metadata. To promote better use...

Protein structure prediction has been a “grand challenge” problem in the structure biology over the last few decades. Protein quality assessment plays a very important role in protein structure prediction. In the paper, we propose a new protein quality assessment method which can predict both local and global quality of the protein 3D structural models. Our method uses both multi and single mod...

Techniques for assessing data quality along different dimensions have been discussed in the data quality management (DQM) literature. In recent years, researchers and practitioners have underscored the importance of contextual quality assessment, highlighting its contribution to decision-making. The current data quality measurement methods, however, are often derived from impartial data and sys...

Several metrics have been proposed in literature to assess the perceptual quality of two-dimensional images. However, no similar effort has been devoted to quality assessment of stereoscopic images. Therefore, in this paper, we review the different issues related to 3D visualization, and we propose a quality metric for the assessment of stereopairs using the fusion of 2D quality metrics and of ...

This work focuses on considering motion towards improving video quality assessment algorithms. The improvement refers to improving computational video quality assessment algorithms in order to be in closer agreement with the subjective evaluation of video quality. We propose a motion saliency model that exploits motion features on spatial level and also an approach for consideration of global m...

background and objectives: there is a growing tendency in iran’s health sector for adoption of standard excellence models for improving quality in healthcare organizations. the european foundation of quality management (efqm) model is a widely used framework for continuous quality management within healthcare facilities. the purpose of this article is to extend the view of current status of qua...
