In multimodal presentations the perceived audiovisual quality assessment is significantly influenced by the content of both the audio and visual tracks. Based on our earlier subjective quality test for finding the optimal trade-off between audio and video quality, this paper proposes a novel method for relative multimodal complexity analysis to derive the fusion parameter in objective audiovisual...
It is known that peak signal-to-noise ratio (PSNR) can be used for assessing the relative qualities of distorted video sequences meaningfully only if the compared sequences contain similar types of distortions. In this paper, we propose a model for rough assessment of the bias in PSNR results, when video sequences with both channel and source distortion are compared against video sequences with source...
Objective metrics are widely used to estimate the perceived quality of audio and video content in consumer electronics applications. Although a number of such metrics exist, they have all been developed for the unimodal case-cross-modal interaction, i.e. the influence of video on audio and vice versa, is not considered by these metrics. We give an overview on these, and summarize human audiovisual...
