This paper presents recommended techniques for choosing video sequences for subjective experiments. Subjective video quality assessment is a well-understood field, yet scene selection is often driven by convenience or content availability. Three-dimensional testing is a newer field that requires new considerations for scene selection. The impact of experiment design on best practices for scene ...

background: citizenship education is increasingly considered as an important strategy to empower youths in taking responsibilities and playing their individual and social roles, and to protect them against psychosocial pathologies. the purpose of the present descriptive study was to investigate students’ levels of knowledge,  their intention, subjective norms, and attitudes toward the character...

The complexity of an image tells many aspects of the image content and is an important factor in the selection of source material for testing various image processing methods. Databases of pictures or videos explained with subjective evaluations constitute basic ground truth for preparing, testing, what's more, benchmarking calculations for target quality appraisal. We propose a few criteria fo...

Image quality of the compressed pictures can be evaluated by objective testing method based on the lower level human visual system model. The simulation of the HVS model presented here is used either to show the region in a compressed picture where the distortion is visible or can produce a single image quality number which correlates well with subjective image quality evaluation. Sets of the p...

BACKGROUND High infection rates of STIs are found among the different ethnic communities living in the Netherlands, especially among the Surinamese and Dutch-Antilleans. Only limited effective interventions that promote STI/HIV testing among these communities are available in the Netherlands. In the present study we identified the determinants of the intention to get tested for STI/HIV of the s...

The purpose of this study was to examine the relation between the subjective report of feeling foggy at one-week post concussion and acute neuropsychological outcome. The outcome variables were derived from a computerized neuropsychological screening battery, Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Participants were 110 high school students who sustained a sports-re...

BACKGROUND The purpose of the study was to assess the effect of trimetazidine administered for 20 days in 56 patients with ischemic heart disease treated with maximal tolerated doses of anti-ischemic drugs who were not candidates for percutaneous or surgical revascularization. METHODS The efficacy of trimetazidine was evaluated by comparing exercise testing parameters before and after treatme...

The objective of this study was to examine differences in neurocognitive performance between symptomatic concussed athletes, a group of concussed athletes with no subjective symptoms, and a non-concussed control group of athletes. All concussed athletes were evaluated within one week of injury using the ImPACT computerized test battery. Results indicate that concussed athletes who denied subjec...

Collecting and grouping customer needs and constraints by similarity are essential steps in market-driven product development. This paper introduces an overall procedure to collect and structure customer needs and constraints with the emphasis on grouping customer needs by similarity. In particular, this paper applies a statistical methodology (Subjective Clustering) to test for an indication t...

To avoid motion artefacts when merging multiple exposures into an HDR image, a number of deghosting algorithms have been proposed. These algorithms, however, do not work equally well on all types of scenes, and some may even introduce additional artefacts. Even though subjective methods of evaluation provide reliable means of testing, they need to be repeated for each new proposed method or eve...
