ABSTRACT:
An advanced noise estimation method is provided. The noise estimation method includes calculating motion compensation information of the input picture at a first resolution, calculating the motion compensation information of the input picture at a second resolution, and based on the motion compensation information at the first resolution and the motion compensation information at the second resolution, estimating the noise of the input picture.
