NO-REFERENCE VISUAL MEDIA ASSESSMENT COMBINING DEEP NEURAL NETWORKS AND MODELS OF HUMAN VISUAL SYSTEM AND VIDEO CONTENT/DISTORTION ANALYSIS

摘要

No-reference (NR) quality assessment (VQA) of a test visual media input encoding media content is provided. The test video visual media input is decomposed into multiple-channel representations. Domain knowledge is obtained by performing content analysis, distortion analysis, human visual system (HVS) modeling, and/or viewing device analysis. The multiple-channel representations are passed into deep neural networks (DNNs) producing DNN outputs. The DNN outputs are combined using domain knowledge to produce an overall quality score of the test visual media input.
