We carried out crowdsourced video quality assessments using paired comparisons and converting the results to differential mean opinion scores (DMOS). A previous labbased study had provided corresponding MOS-values for absolute category ratings. Using a simple linear transformation to fit the crowdsourcing-based DMOS values to the lab-based MOS values, we(More)
We study the use of crowdsourcing for self-reported attention in image quality assessment (IQA) tasks. We present the results from two crowdsourcing campaigns: one where participants indicated via mouse clicks the image locations that influenced their rating of quality, and another where participants chose locations they looked at in a free-viewing setting.(More)
Subjective video quality assessment (VQA) strongly depends on semantics, context, and the types of visual distortions. Currently, all existing VQA databases include only a small number of video sequences with artificial distortions. The development and evaluation of objective quality assessment methods would benefit from having larger datasets of real-world(More)
