Abstract
Embodiments of the present disclosure provide methods and apparatuses for removing video jitter. The method can include: determining position information of feature point pairs in each pair of raw images according to position information of feature point pairs in each pair of compressed images, wherein one feature point pair is composed of two corresponding feature points on two consecutive images in each pair of images, and the raw images are uncompressed images; determining position change information of a subsequent image relative to a preceding image in each pair of raw images according to the position information of the feature point pairs in each pair of raw images; acquiring deformation information corresponding to the preceding image in a m-th pair of raw images according to the position change information of the subsequent image relative to the preceding image inn pairs of raw images, wherein n and m are positive integers, and m is not greater than n; and deforming the preceding image in the m-th pair of raw images according to the deformation information corresponding to the preceding image in the m-th pair of raw images for removing jitter in the preceding image in the m…
