Abstract:
A method for estimating noise in a series of video frames includes selecting a region of a first frame, calculating high frequency quantities for the selected region, calculating temporal-domain high frequency quantities for the selected region of the frame and a mapping region of a second frame, and generating a noise estimate of the noise according to a relationship between the high frequency quantities and the temporal-domain high frequency quantities.
