The Effects of Jitter on the Perceptual Quality of Video

by Mark Claypool, Jonathan Tanner - IN PROCEEDINGS OF THE ACM MULTIMEDIA CONFERENCE , 1999
"... Today's powerful computers and networks present the opportunity for video across the Internet right to the desktop. However, Internet video often suffers from packet loss and jitter, degrading the user's perceived quality of the video. The effects of packet loss on perceptual quality are w ..."

AN EFFICIENT PERCEPTUAL QUALITY INDEX METRICS

by D. Neelima, Shaika Sultana
"... In Human Visual System (HVS) video quality assessment is more important. We have studied HVS, we observed non systematic and impairing of videos in that. So we propose a novel approach that is called Perceptual quality index based on video quality assessment(VQS).In this paper visual performance equ ..."

Perceptual Quality Adaptation (pqa) Algorithm

by For Gp And, Nicola Cranley, Liam Murphy, Philip Perry - Proc. 15 th IEEE Intl. Symp. on Personal, Indoor and Mobile Radio Communications , 2004
"... Many adaptive delivery mechanisms have been devised for streaming multimedia over best-effort IP networks, such as the Internet. Most of these adaptive schemes do not consider the user's perception of quality when making adaptations. We describe a Perceptual Quality Adaptation algorithm (PQA) a ..."

Segmentation-driven perceptual quality metrics

by Andrea Cavallaro, Stefan Winkler - Proceedings, IEEE Int. Conf. on Image Processing, 2004
"... We present a full-reference and a no-reference percep-tual video quality metric that incorporate both low-level and high-level aspects of vision. Low-level aspects include color perception, contrast sensitivity, masking as well as artifact analysis. High-level aspects take into account the cognitive ..."

Visualization of perceptual qualities in textural sounds

by Thomas Grill, Arthur Flexer - in Proceedings of the International Computer Music Conference (ICMC 2012 , 2012
"... We describe a visualization strategy that is capable of effi-ciently representing relevant perceptual qualities of textu-ral sounds. The general aim is to develop intuitive screen-based interfaces representing large collections of sounds, where sound retrieval shall be much facilitated by the ex-plo ..."

Measuring the Perceptual Quality of Skype Sources

by unknown authors
"... The success of Skype has inspired a generation of peer-to-peer-based solutions for real-time multimedia services over the Internet. However, there lacks still a robust metric quantifying the percep-tual quality of a Skype call. The widely-used PESQ (Perceptual Evaluation of Speech Quality) falls sho ..."

Perceptual quality assessment for video watermarking

by Stefan Winkler, Elisa Drelie Gelasca, Touradj Ebrahimi - in Proceedings of the International Conference on Information Technology: Coding and Computing , 2002
"... The reliable evaluation of the performance of watermarking algorithms is difficult. An important aspect in this process is the assessment of the visibility of the watermark. In this paper, we address this issue and propose a methodology for evaluating the visual quality of watermarked video. Using a ..."

Controlled and automatic human information processing: II. Perceptual learning, automatic attending and a general theory

by Richard M. Shiffrin, Walter Schneider - Psychological Review , 1977

The two-process theory of detection, search, and attention presented by Schneider and Shiffrin is tested and extended in a series of experiments. The studies demonstrate the qualitative difference between two modes of information processing: automatic detection and controlled search. They trace the course of the learning of automatic detection, of categories, and of automaticattention responses. They show the dependence of automatic detection on attending responses and demonstrate how such responses interrupt controlled processing and interfere with the focusing of attention. The learning of categories is shown to improve controlled search performance. A general framework for human information processing is proposed; the framework emphasizes the roles of automatic and controlled processing. The theory is compared to and contrasted with extant models of search and attention.
