摘要：
Embodiments of the present invention provides a method and device for processing a source video. The method and device may provide computing an artifact estimation from differences among pixels selected from spatially-distributed sampling patterns in the source video; filtering the source video to produce a filtered version of the source video, computing a blending factor based on the artifact estimation in the source video, and computing an output video by blending the source video and the filtered version of the source video based on the blending factor.
