Methodology for Quantifying the Flicker Effect in Video Compression

The present tendency is for streaming video to consume increasingly more bandwidth on the Internet. In recent years, interest toward the development of models for objectively assessing video quality has been on a highly growing trend. Objective assessments of video quality developed on models of the human visual system have been successful in describing static spatiotemporal coding. However, much less attention has been paid to the question concerning the way the visual areas of the brain process temporary information masking in motion. Stroboscopic effects in television have been well studied for lower frequencies, but knowledge of higher frequencies is needed for streaming video as well as the complex temporal spectra, which occur with simultaneous motion and flicker of objects. In the presented research, a methodology and equipment were developed to quantify the flicker effect in video compression, specifically, information on the response to motion masking for high temporal frequencies, or, in other words, information hiding in motion in today’s video content presentation environment.
