| Abstract(in English) | Image restoration, which is an inverse problem such as compressed sensing and super-resolution, requires priors (e.g. Total Variation minimization) for regularization. In this paper, we propose a new image restoration method using a lossy image codec. With a prior which is implicitly defined by an off-the-shelf image codec (e.g HEIF), the proposed method can recover targets efficiently. In our experiment, the proposed method outperformed hand-crafted prior-based methods. |
