Abstract
A method includes obtaining a to-be-processed current point in a target area in a current frame, obtaining a first-type smoothing weight of a first-type neighborhood point in an Nth frame before the current frame with respect to the current point, where the first-type neighborhood point is an Xth circle point that encircles a point corresponding to a location of the current point and that is in the Nth frame before the current frame, obtaining a second-type smoothing weight of a second-type neighborhood point in an Mth frame after the current frame with respect to the current point, where the second-type neighborhood point is a Yth circle point that encircles the point corresponding to the location of the current point and that is in the Mth frame after the current frame, and performing smoothing calculation on the current point according to the first-type smoothing weight and the second-type smoothing weight.
