Abstract :
Over the past decade, video acquisition rates, which had been 24 Hz (cinema), 30-60 Hz (webcam) or 50-60 Hz (SD/HDcam), has broken through to reach 1000 Hz. In order to display these high frame-rate video signals on current display devices in real time, they must be down-sampled first. This study proposes a down-sampling method suitable for high frame-rate video signals. It is designed with the goal of reducing the inter-frame prediction error. Our method can improve the PSNR of prediction signal by 0.13 [dB] to 0.23 [dB] compared to simple sub-sampling with constant interval.
