Robust Dynamic Super Resolution under Inaccurate Motion Estimation

Abstract

In image reconstruction, dynamic super resolutionimage reconstruction algorithms have been investigated toenhance video frames sequentially, where explicit motionestimation is considered as a major factor in theperformance. This paper proposes a novel measurementvalidation method to attain robust image reconstructionresults under inaccurate motion estimation. In addition, wepresent an effective scene change detection methoddedicated to the proposed super resolution technique forminimizing erroneous results when abrupt scene changesoccur in the video frames. Representative experimentalresults show excellent performance of the proposedalgorithm in terms of the reconstruction quality andprocessing speed.
