Improving the Prediction Accuracy of Objective Video Quality Evaluation

Objective evaluation of video segmentation quality

Video segmentation assumes a major role in the context of object-based coding and description applications. Evaluating the adequacy of a segmentation result for a given application is a requisite both to allow the appropriate selection of segmentation algorithms as well as to adjust their parameters for optimal performance. Subjective testing, the current practice for the evaluation of video se...

Objective Evaluation of the Perceived Quality of Video Content

This paper presents a method for the objective evaluation of the perceived quality of video content. The proposed method is based on the experimental measurement of a simple metric derived from the encoding and playback of a short video clip in MPEG-4 format. Implementation and tests have been performed in the frame of the IST/SOQUET project

The Content Based Objective Metrics for Video Quality Evaluation

Objective Video Quality Assessment

Digital video data, stored in video databases and distributed through communication networks, is subject to various kinds of distortions during acquisition, compression, processing, transmission, and reproduction. For example, lossy video compression techniques, which are almost always used to reduce the bandwidth needed to store or transmit video data, may degrade the quality during the quanti...

An evaluation of objective quality measures for speech intelligibility prediction

In this research various objective quality measures are evaluated in order to predict the intelligibility for a wide range of non-linearly processed speech signals and speech degraded by additive noise. The obtained results are compared with the prediction results of a more advanced perceptual-based model proposed by Dau et al. and an objective intelligibility measure, namely the coherence spee...
