ARM-based real-time video stabilization enhancement algorithm

Considering the performance characteristic of ARM processor, an ARM-based real-time video stabilization enhancement algorithm was proposed that identified shakiness of video and implements motion smoothing in the space of geometric transformations. The algorithm identified the shakiness of video with the amplitudes' change of translation and rotation. Then the optimal path could be obtained by linear interpolation on translational vector and rotational angle. Stable frames were generated by implementing motion compensation of translation and rotation transformations respectively. Because the algorithm used linear interpolation in the space of rigid transformations, it was much faster than the previous algorithms. Moreover, it could control cropping ratio in motion compensation and guarantee no extra distortion drawn into the warped frames. Experiments show that the algorithm can stabilize video based on ARM platform in real time and obtain good video stabilization as well.
