Abstract:
1. A method comprising: receiving an input video; and performing operations to reduce one or both of noise and flicker in the input video using spatial and temporal processing by applying a spatial transform to transform a sub-frame of a current frame of the input video into a spatial transform domain, thresholding spatial-transform coefficients of the sub-frame, applying a temporal transform with adaptive thresholding of the thresholded spatial-transform coefficients, inverse transforming spatial-transform coefficients to obtain a processed sub-frame, and combining the processed sub-frame with previously processed sub-frames belonging to the current frame to create a new frame of an output video, wherein applying the spatial transform and the temporal transform comprises applying at least one pixel-adaptive warped transform to the sub-frame to create transform coefficients.
