Abstract:
Disclosed is a video stabilization method including steps of selecting a first area in a first image; determining at least one first feature point based on the first area, and performing feature point matching on the first image and a second image so as to obtain at least one feature point matching pair between the first image and the second image, each feature point matching pair including a first feature point of the first image and a second feature point of the second image; conducting motion parameter estimation based on the at least one feature point matching pair so as to obtain a motion parameter; and carrying out motion compensation with respect to the first image based on the motion parameter so as to acquire a first stable image after compensation.
