摘要翻译：
深度学习在过去几年里导致了超分辨率(SR)性能的戏剧性飞跃。然而，在监督下，这些SR方法被限制于特定的训练数据，其中从它们的高分辨率(HR)对应物中获取低分辨率(LR)图像是预先确定的（例如，双三次降尺度），而没有任何分散注意力的伪影（例如，传感器噪声、图像压缩、非理想PSF等）。然而，真实的LR图像很少遵守这些限制，导致SotA（State of the Art）方法的SR结果很差。在本文中，我们介绍了“零镜头”SR，它利用了深度学习的力量，但不依赖于先验训练。我们利用单个图像中信息的内部递归性，并在测试时间对仅从输入图像本身提取的示例训练一个小的图像特定的CNN。因此，它可以使自己适应每个图像的不同设置。这允许执行真实的老照片，噪声图像，生物数据，和其他图像的采集过程未知或非理想的SR。在这样的图像上，我们的方法优于基于SotA CNN的SR方法，以及以前的无监督SR方法。据我们所知，这是第一个无监督的基于CNN的SR方法。

英文摘要：
  Deep Learning has led to a dramatic leap in Super-Resolution (SR) performance in the past few years. However, being supervised, these SR methods are restricted to specific training data, where the acquisition of the low-resolution (LR) images from their high-resolution (HR) counterparts is predetermined (e.g., bicubic downscaling), without any distracting artifacts (e.g., sensor noise, image compression, non-ideal PSF, etc). Real LR images, however, rarely obey these restrictions, resulting in poor SR results by SotA (State of the Art) methods. In this paper we introduce "Zero-Shot" SR, which exploits the power of Deep Learning, but does not rely on prior training. We exploit the internal recurrence of information inside a single image, and train a small image-specific CNN at test time, on examples extracted solely from the input image itself. As such, it can adapt itself to different settings per image. This allows to perform SR of real old photos, noisy images, biological data, and other images where the acquisition process is unknown or non-ideal. On such images, our method outperforms SotA CNN-based SR methods, as well as previous unsupervised SR methods. To the best of our knowledge, this is the first unsupervised CNN-based SR method.
