Abstract:

This paper proposes a deflicker algorithm based on multiframe reference of blocked video. The algorithm estimates every block’s flicker gain by considering the temporal change in multiframes to adjust intensity of the current frame by using this flickgainmodel. We design a motion detector to correct motion blur caused by the adjustment of the flicker model. The algorithm can effectively remove video flicker and has low computation complexity therefore faster processing speed.

Key words: video restore; flicker restore; block restore; multiframe restore
