dc.description.abstract This paper proposes an example-based method to increase the resolution of a low-resolution image. In the proposed method, we generate example images by a novel view synthesis technique using 3D geometry reconstruction and camera pose estimation from a video or images capturing the same scene. We then increase the resolution by minimizing an energy function by searching for the optimal example from the generated example images. The proposed method has less limitations on camera positions and geometry of the target scene than those in conventional methods. Experiments demonstrate the effectiveness of the proposed method by qualitatively comparing the results of the proposed and conventional methods. en
