Audiovisual quality evaluation of low-bitrate video
نویسندگان
چکیده
Audiovisual quality assessment is a relatively unexplored topic. We designed subjective experiments for audio , video, and audiovisual quality using content and encoding parameters representative of video for mobile applications. Our focus were the MPEG-4 AVC (a.k.a. H.264) and AAC coding standards. Our goals in this study are twofold: we want to understand the interactions between audio and video in terms of perceived audiovisual quality, and we use the subjective data to evaluate the prediction performance of our non-reference video and audio quality metrics.

Experienced Quality Factors - Qualitative Evaluation Approach to Audiovisual Quality
Subjective evaluation is used to identify impairment factors of multimedia quality. The final quality is often formulated via quantitative experiments, but this approach has its constraints, as subject’s quality interpretations, experiences and quality evaluation criteria are disregarded. To identify these quality evaluation factors, this study examined qualitatively the criteria participants u...
متن کاملTowards Bandwidth Efficient Adaptive Streaming of Omnidirectional Video over HTTP: Design, Implementation, and Evaluation
Real-time entertainment services such as streaming audiovisual content deployed over the open, unmanaged Internet account now for more than 70% during peak periods. More and more such bandwidth hungry applications and services are proposed like immersive media services such as virtual reality and, specifically omnidirectional/360-degree videos. The adaptive streaming of omnidirectional video ov...
متن کاملFocus of attention: Towards low bitrate video tele-conferencing
Low bitrate video tele-conferencing requires adapting algorithms that may work perfectly well in a high-bitrate situation. When a slow transmission rate is unacceptable, compromise must be reached among the demands of speed, bandwidth limits and image quality. In this paper we present an approach to low bitrate video teleconferencing by focus-ing attention on important information. We show that...
متن کاملImage Analysis Towards Very Low Bitrate Video Coding
Very low bitrate video coding became in the last years one of the most important areas of image communication due to the identification of several very low bitrate applications such as mobile videotelephony, multimedia mail, electronic newspapers, entertainment, traffic control, and interactive data bases. Since conventional video coding techniques are reaching a saturation point, a new generat...
متن کاملNew Half-Pixel Accuracy Motion Estimation Algorithms for Low Bitrate Video Communications
Fractional-pixel accuracy Motion Estimation (ME) has been shown to result in higher quality reconstructed image sequences in hybrid video coding systems. However, the higher quality is achieved by notably increased Motion Field (MF) bitrate and more complex computations. In this paper, new half-pixel block matching ME algorithms are proposed to improve the rate-distortion characteristics of low...
