A SURVEY ON VIDEO STABILIZATION TECHNIQUES

In computer vision, video stabilization is an image processing method to remove visually distributing shaky or unstable motions from videos. This image disturbance may be due to the handshake of the camera holder or platform vibrations in case of surveillance cameras. In order to remove these unsteady motions, video stabilization contains three major step Motion estimation, Motion compensation or Motion smoothing, and Image warping. There are mainly four categories of video stabilization viz., optical stabilization, electronic stabilization, mechanical stabilization, digital stabilization. Digital video stabilization techniques make use only of information drawn from already captured footage and do not need any additional hardware or knowledge about camera physical motion, making it inexpensive and relatively easy to use. Video stabilization is used for astrophotography, tracking targets in military, earth motion etc. Many approaches of video stabilization
