  • Enhancing low quality videos of illuminated scenes
    Patent number: 7359562
    Abstract: A method enhances a low quality video. An input video Vjin is acquired of a scene under uncontrolled illumination. The input video Vjin is smoothed to produce a noise-reduced video Sj. Temporal gradients Gtj (x, y) are determined for each frame j of the noise reduced video Sj. The gradients Gtj (x, y) are thresholded to generate a binary mask Mj(x, y). For each frame, weights are determined according Wj (x, y)=F(Mk(x, y), and a spatial gradient field is determined according to Gxyj (x, y). Then, an output video Vjout is constructed from the spatial gradient field Gxyj.
