It is well known that the perception of the position of audio and video stimuli is not independent. In general, video dominates the position if the position offset between audio and video is small. Most previous work focused on natural listening conditions and position offsets between audio and video in the horizontal plane. There is little research concerning offsets in vertical direction and ...

OBJECTIVE To protect minors from exposure to video games with objectionable content (eg, violence and sex), the Pan European Game Information developed a classification system for video games (eg, 18+). We tested the hypothesis that this classification system may actually increase the attractiveness of games for children younger than the age rating. PARTICIPANTS AND METHODS Participants were ...

conclusions the study results are indicative of the impact of electromagnetic fields on computer users’ health, and it is thus advisable to avoid leaving computers switched on unnecessarily in addition to observing the minimum distance of 60 cm from computer monitors to control the adverse effects of electromagnetic fields. materials and methods electric and magnetic field intensities were meas...

Subjects with central field loss (CFL) individually selected enhancement parameters to improve visibility of static video images. The effect of enhancement on performance and on perceived quality of motion video was assessed. Performance, e.g. recognition of visual details, was assessed by having subjects answer questions regarding visual information contained in the video motion segments that ...

Video sequences contains multiple frames therefore their quality is estimated by determining individual quality metric of each frame then apply the temporal masking affect. However, the integration of each frame’s quality metric into one score is very important because each video frame has different spatial features hence have different quality metric. There are several methods available to com...

In asymmetric stereoscopic video compression, the views are coded with different qualities. According to the binocular suppression theory, the perceived quality is closer to that of the higher-fidelity view. Hence, a higher compression ratio is potentially achieved through asymmetric coding. Furthermore, when mixed-resolution coding is applied, the complexity of the coding and decoding is reduc...

Abstract: From anesthetized rats in the 90s to conscious wild-type or knockout mice today, intracerebral in vivo microdialysis provided important information about the brain mechanism of action of psychotropic drugs such as antidepressants. The principle of microdialysis technique is based on the balance between the release of neurotransmitters (e.g., serotonin 5-HT, norepinephrine, dopamine) a...

The aim of this study was to validate the use of three models of fracture fixation in the assessment of technical skills. We recruited 21 subjects (six experts, seven intermediates, and eight novices) to perform three procedures: application of a dynamic compression plate on a cadaver porcine model, insertion of an unreamed tibial intramedullary nail, and application of a forearm external fixat...

A new highly adaptable model for predicting human vision response is presented for enabling an improved method of predicting subjective video quality. The ability to adapt enables comparison of video with dissimilar image sizes, viewing environments, frame rates, video quality classes, etc. (for example HD vs. SD vs. CIF). Model test results are compared with human response. Responses are from ...
