Center node: "a jnd based video quality assessment model and its application"
  Abstract: Based on the Just-Noticeable-Difference (JND) criterion, a subjective video quality assessment (VQA) dataset, called the VideoSet, was constructed recently. In this work, we propose a JND-based VQA model using a probabilistic framework to analyze and clean collected subjective test data. While most traditional VQA models focus on content variability, our proposed VQA model takes both subject and content variabilities into account. The model parameters used to describe subject and content variabilities are jointly optimized by solving a maximum likelihood estimation (MLE) problem. As an application, the new subjective VQA model is used to filter out unreliable video quality scores collected in the VideoSet. Experiments are conducted to demonstrate the effectiveness of the proposed model.

Connected through hyperedge HE-1 (induced by source paper "a user model for jnd based video quality assessment theory and applications"):
  with members:
    - "a perceptually weighted rank correlation indicator for objective image quality assessment"
    - "videoset a large scale compressed video quality dataset based on jnd measurement"
    - "prediction of satisfied user ratio for compressed video"
    - "recover subjective quality scores from noisy measurements"
