    End user quality perception in the context of Internet applications is often characterized by waiting times before service consumption as well as interruptions during service consumption. In particular in case of bad network conditions, network and service providers have to trade off between these two impairment types, i.e. between the devil and the deep blue sea. In this paper we investigate this... View full abstract»

  • No-reference bitstream-based impairment detection for high efficiency video coding

    Video distribution over error-prone Internet Protocol (IP) networks results in visual impairments on the received video streams. Objective impairment detection algorithms are crucial for maintaining a high Quality of Experience (QoE) as provided with IPTV distribution. There is a lot of research invested in H.264/AVC impairment detection models and questions rise if these turn obsolete with a tran... View full abstract»

    Video quality evaluation with subjective testing is both time consuming and expensive. A promising new approach to traditional testing is the so-called crowdsourcing, moving the testing effort into the Internet. The advantages of this approach are not only the access to a larger and more diverse pool of test subjects, but also the significant reduction of the financial burden. Recent contributions...

    Controlled subjective quality experiments are a well-known method to make decisions on the improvement of Quality of Service (QoS) of video streams. Recently it became clear that from a point of view of the consumer or user, the Quality of Experience (QoE) is more relevant and can influence the optimal QoS as determined in a lab-setting. The measurement of QoS parameters in a lab-setting does not ... View full abstract»

  • Optimizing image quality in MRI: On the evaluation of k-space trajectories for under-sampled MR acquisition

    Modern magnetic resonance (MR) applications require high-speed acquisitions. One of the possible ways to accelerate the process is to acquire the data along a k-space trajectory at sub-Nyquist rate and then reconstruct the image by an iterative non-linear reconstruction algorithm. The choice of k-space trajectory and its parameters has a large influence on the image quality. For physicians it is m... View full abstract»

    In this paper, we present and define aesthetic principles for the automatic generation of media galleries based on media items retrieved from social networks that-after a ranking and pruning step-can serve to authentically summarize events and their atmosphere from a visual and an audial standpoint.

    This short paper presents a perspective plan to build a null reference image quality assessment. Its main goal is to deliver both the objective score and the distortion map for a given distorted image without the knowledge of its reference image. View full abstract»

  • VITEQ: A generic framework for no-reference quality evaluation of video testimonials

    Publication Year: 2012, Page(s):33 - 34
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (100 KB) | HTML iconHTML

    This paper proposes a generic framework for no-reference quality evaluation of video testimonials. The global quality of the video testimonials is estimated by fusing the individual scores of a selection of spatial, temporal, audio and content-related metrics. Based on the global quality score, feedback is given to the user and the video/audio quality improver can be activated. Experiments on a la... View full abstract»

    Subjective laboratory tests represent a proven, reliable approach towards multimedia quality assessment. Nonetheless, in certain cases novel progressive quality of experience (QoE) assessment methods can lead to better results or enable test execution in more cost-effective ways. In this respect, crowdsourcing can be considered as emerging method enabling researchers to better explore end-user qua... View full abstract»
