Document Type and Number:
WIPO Patent Application WO/2020/147423
Kind Code:
A1
Abstract:
The present disclosure is related to systems and methods for noise reduction. The method includes determining a first image block in each of a group of continuous frames including a current frame and a plurality of reference frames based on coordinates of a target pixel in the current frame. The method includes determining at least one second image block corresponding to the first image block in each of the group of continuous frames. The method includes determining an average offset between the at least one second image block in the current frame and the second image blocks in the plurality of reference frames. The method includes determining a spatial domain filtering intensity and a temporal domain filtering intensity for the target pixel in the current frame.
