To quantify the excellence of multimedia quality, subjective evaluation experiments are conducted. In these experiments, the tradition of quantitative assessment is the most dominating, but it disregards the understanding of participants’ interpretations, descriptions, and the evaluation criteria of quality. The goal of this paper is to present a new multimedia quality evaluation method called ...

Impacts of poor quality of information are felt at every level in an organisation. To mitigate these impacts, information quality must be assessed and managed. However, obtaining accurate measurements and cost-effective assessments of information quality have proven to be an extremely difficult task due to the complexities of information systems and the various information quality dimensions de...

It is important to transmit pictures efficiently in most Web sites, especially for those users with low bandwidth connections. In this demonstration, we propose a system which progressively transmits images using a very low transmission rate (as low as 15% in some cases). The transmitted images maintain a reasonable picture quality for the users to browse images quickly. Interested readers can ...

The ITU Radiocommunication Assembly, considering a) that with the increasing application of digital coding and bit-rate reduced transmission, the assessment of coding impairments is of critical importance; b) that objective measurements are necessary for specific evaluations as routine supervisions or system optimizations; c) that several types of objective measurements may be defined for diffe...

Sound quality usually can be described by psychoacoustic magnitudes like loudness, sharpness or roughness. However, sometimes the meaning of a sound may strongly influence its subjective evaluation. In order to assess these effects, sounds „without meaning“ have to be realized. A frequently applied solution of this problem is to fill the temporal envelope of an original sound with pink noise. H...
