Abstract

We present a method for enhancing videos with invisibly subtle time-variation. Temporal unsharp masking is applied to videos. This unsharp masking is of band-amplifying type where time-variation is computed by subtracting a doubly-smoothed video from a singly-smoothed one. Noise is reduced by spatially smoothing of each frame in the video using the cross bilateral filter. This method preserves the hue of each frame in videos.
