In image reconstruction, dynamic super resolution image reconstruction algorithms have been investigated to enhance video frames sequentially, where explicit motion estimation is considered as a major factor in the performance. This paper proposes a novel measurement validation method to attain robust image reconstruction results under inaccurate motion estimation. In addition, we present an effective scene change detection method dedicated to the proposed super resolution technique for minimizing erroneous results when abrupt scene changes occur in the video frames. Representative experimental results show excellent performance of the proposed algorithm in terms of the reconstruction quality and processing speed.
