In order to overcome image shakes in the video of the camera mounted on the aerial platform, an improved feature estimation was proposed to remove effectively the inter frame jitter of the video sequences and to realize the electronic image stability. An algorithm combining scalespace FAST corner detector and improved SURF descriptor , is proposed in this paper. The video rotation is removed ,and the stable feature points of neighbor frames was extracted and the estimation of inter frame motion vectors was implemented. RANSAC was employed to solve the global motion vectors. Quadratic interpolation algorithm is adopted to get the stable video. The experimental result indicates that the PSNR of video sequence has improved about 5 db, which verifies that the proposed stabilized algorithm removes interframe jitter under complicated movement ,higher accuracy and stronger robustness.
