New framework stress-tests outlier detection in image quality assessment

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new framework for stress-testing outlier detection methods used in subjective image quality assessment. This framework employs adversarial attacks to identify ratings that maximize discrepancies in Mean Opinion Score (MOS) estimates. The study demonstrates significant differences in the worst-case performance of various outlier detection methods under these adversarial conditions and proposes new, low-complexity methods that exhibit strong empirical worst-case performance. AI

IMPACT Introduces novel methods for robust data validation in image quality assessment, potentially improving the reliability of AI models trained on such data.

    Adversarial Stress Testing of Outlier Detection in Subjective Image Quality Assessment

    arXiv:2509.06554v2 Announce Type: replace-cross Abstract: In subjective image and video quality assessment, observers rate or compare selected stimuli. Before calculating mean opinion scores (MOSs), unreliable ratings should be identified and handled as outliers. Several outlier-…
