Stabilization, restoration and resolution enhancement of a video sequence captured by a moving and vibrating platform

Abstract

Image sequences recorded from moving platforms are often distorted by undesired motion. The image motion within a video sequence captured from a moving platform is compounded in general from a smooth component such as camera panning and a high frequency component such as mechanical vibration or shocks. The undesired high frequency component of the motion may affect severely the perception of the image sequence content. This motion component causes two types of distortion. The first is the unexpected scene change caused by motion and vibration of the line-of-sight from frame to frame. The second effect is blur of each frame of the sequence due to frame motion during its exposure. In this work we propose an algorithm that eliminates the undesired component of the motion and increases the spatial resolution of each frame in the image sequence. The resolution is increased by deblurring the images and by utilizing information within adjacent frames with superresoluion restoration techniques.
