Enhancing Video Quality Assessment Through Temporal Visual Masking Analysis

This paper introduces a novel FS-MOVIE model for video quality assessment, focusing on the impact of temporal visual masking on local flicker. The model incorporates motion silencing illusion and V1 cortical neuron responses to improve video integrity evaluation and perceptual visibility index. Through experiments, the study examines the effect of bit rate, motion, temporal pooling, and computational complexity, concluding that the FS-MOVIE framework enhances the assessment accuracy.
