Abstract
A video image processing method and apparatus is described. The method includes obtaining a first key point of an Mth frame image in a video. The method further includes performing weighted smoothing on the first key point of the Mth frame image according to first key points in a historical key point queue and weights in a first target weight queue, to obtain a target key point. The historical key point queue includes a first key point corresponds to each frame image in N frame images. The N frame images are images before the Mth frame image, N>0. The weights in the first target weight queue corresponding to the first key points in the historical key point queue, A weight corresponding to a first key point of an (M-a)th frame image being greater than or equal to a weight corresponding to a first key point of an (M-b)th frame image, and a<b. The method further includes adjusting the Mth frame image according to the target key point.
