In this letter, we propose a solution to both issues by combining a nonlocal algorithm with a lightweight residual CNN.

In this paper, we highlight the importance of large objects in learning features that are critical for all sizes.

Unfortunately the lack of reliable high-resolution (HR) ground truth limits the application of deep learning methods to this task.

In this paper we will focus on the depth information, which can be obtained by using a depth estimation network or measured from available data (stereovision, parallax motion, LiDAR, etc.).

Modern Earth observation satellites capture multi-exposure bursts of push-frame images that can be super-resolved via computational means.

We argue that in doing so, the challenge ranks the proposed methods not only by their MISR performance, but mainly by the heuristics used to guess which image in the series is the most similar to the high-resolution target.

We propose a self-supervised approach for training multi-frame video denoising networks.

Denoising is an essential part of any image- or video-processing pipeline.

Due to the unavailability of ground truth data these networks cannot be currently trained using real RAW images.

Anomaly detectors address the difficult problem of detecting automatically exceptions in an arbitrary background image.

To the best of our knowledge, this is the first successful application of a CNN to video denoising.

Modeling the processing chain that has produced a video is a difficult reverse engineering task, even when the camera is available.

We review the broad variety of methods that have been proposed for anomaly detection in images.

The two main approaches are statistics-based methods and patch re-arrangement methods.

Finally, we explore a cascade architecture in which the output of a basic CNN is treated as an additional source of information for a subsequent CNN.
