Image Quality Assessment plays an important role in various image processing applications. It is still an active area of research. A great deal of effort has been made in recent years to develop objective image quality metrics that correlate well with perceived human quality measurement or subjective methods. Image quality assessment means estimating the quality of an image and it is used for m...

Depth map upsampling is an approach to increase the spatial resolution of depth maps obtained from ToF (Time of Flight) cameras. Since depth map quality directly affects 3D perception of stereoscopic image, applying different depth upsampling methods to a low resolution depth map causes a variety of perceptions of the stereoscopic images. In this paper, we investigate the relation between objec...

In this paper, the new challenges of 3DTV for subjective assessment are discussed. Conventional 2D methods have severe limitations which will be revealed. Based on the understanding of the new characteristics brought by 3DTV, changes and additions in the requirements for subjective assessment are proposed in order to develop a novel subjective video quality assessment methodology for 3DTV. In p...

Diet is a major lifestyle-related risk factor of various chronic diseases. Dietary intake can be assessed by subjective report and objective observation. Subjective assessment is possible using open-ended surveys such as dietary recalls or records, or using closed-ended surveys including food frequency questionnaires. Each method has inherent strengths and limitations. Continued efforts to impr...

Automatic pre-annotation is often used to improve human annotation speed and accuracy. We address here out-of-domain named entity annotation, and examine whether automatic pre-annotation is still beneficial in this setting. Our study design includes two different corpora, three pre-annotation schemes linked to two annotation levels, both expert and novice annotators, a questionnaire-based subje...

The subjective effects of controlled low frequency limitation of the audio bandwidth on assessment of audio quality were studied. The investigation was focused on the standard 5.1 multichannel audio set-up (Rec. ITU-R BS.775-1) and limited to the optimum listening position. The effect of video presence on audio quality assessment was also investigated. The results of the formal subjective test ...

Subjective assessment may be incomparable across countries due to differences in reporting styles. Based on two nationally representative surveys from the US and China, this study used data from three anchoring vignettes to estimate to what extent the US and Chinese older adults aged 50 and above differed in their reporting styles of subjective cognitive impairment. Cross country differences of...

OBJECTIVE Adverse effects (AEs) of antipsychotic medication have important implications for patients and prescribers in terms of well-being, treatment adherence, and quality of life. This review summarizes strategies for collecting and reporting AE data across a representative literature sample to ascertain their rigor and comprehensiveness. METHODS A PsycINFO search, following preferred repo...

Interpretation of emotional context is a pivotal aspect of understanding social situations. A critical component of this process is assessment of danger levels in the surrounding, which may have a direct effect on the organism's survival. The limbic system has been implicated in mediating this assessment. In situations of uncertainty, the evaluation process may also call for greater involvement...
