Abstract

To overcome the undesirable shakes or jiggles of a camera and to implement the image stabilization in real time

a real-time full-frame video stabilization system based on the Speeded Up Robust Features(SURF) was proposed.Firstly

the SURF was employed to extract feature points

and the correspondence between the current and reference frame was established to get high precision local motion vector estimation. Secondly

by determining the reference frame update strategy

the smoothed interframe global motion vector was obtained. Finally

the corresponding pixels of the reference frame was filled with a stablized frame to compensate the unstable motion and to output an stablized full-frame video. Experimental results show that the real-time full-frame video stabilization system using SURF algorithm can provide the high accuracy (lower than 1 pixel) and short processing time (less than 30 ms). Moreover

it has a higher robustness on serious motion-blur and better image quality.
