Measuring the added high frequency energy in compressed video

A major focus of video quality assessment research has been to quantify the amount of blocking, blurring, and ringing impairments. However, little attention has been paid to another impairment common in motion-compensated video compression systems: the addition of high frequency (HF) energy as motion compensation moves blocking artifacts off block boundaries. In this paper, we employ an energy-based approach to measure this motion-compensated edge artifact (MCEA) impairment, using both compressed bitstream information and decoded pixels. Experimental results show that we can accurately estimate the percentage of this energy in compressed video.
