The 1st edition of AIM: Advances in Image Manipulation workshop will be held November 2, 2019 in conjunction with ICCV 2019 in Seoul, Korea.
Image manipulation is a key computer vision tasks, aiming at the restoration of degraded image content, the filling in of missing information, or the needed transformation and/or manipulation to achieve a desired target (with respect to perceptual quality, contents, or performance of apps working on such images). Recent years have witnessed an increased interest from the vision and graphics communities in these fundamental topics of research. Not only has there been a constantly growing flow of related papers, but also substantial progress has been achieved.
Each step forward eases the use of images by people or computers for the fulfillment of further tasks, as image manipulation serves as an important frontend. Not surprisingly then, there is an ever growing range of applications in fields such as surveillance, the automotive industry, electronics, remote sensing, or medical image analysis etc. The emergence and ubiquitous use of mobile and wearable devices offer another fertile ground for additional applications and faster methods.
This workshop aims to provide an overview of the new trends and advances in those areas. Moreover, it will offer an opportunity for academic and industrial attendees to interact and explore collaborations.
Jointly with AIM workshop we have an AIM challenge on Constrained Super-Resolution, that is, the task of super-resolving (increasing the resolution) an input image with a magnification factor x4 based on a set of prior examples of low and corresponding high resolution images. The challenge has three tracks.
Track 1: Parameters, the aim is to obtain a network design / solution with the lowest amount of parameters while being constrained to maintain or improve the PSNR result and the inference time (runtime) of MSRResNet (Ledig et al, 2017 & Wang et al, 2018).
Track 2: Inference, the aim is to obtain a network design / solution with the lowest inference time (runtime) on a common GPU (ie. Titan Xp) while being constrained to maintain or improve over MSRResNet (Ledig et al, 2017 & Wang et al, 2018) in terms of number of parameters and the PSNR result.
Track 3: Fidelity, the aim is to obtain a network design / solution with the best fidelity (PSNR) while being constrained to maintain or improve over MSRResNet (Ledig et al, 2017 & Wang et al, 2018) in terms of number of parameters and inference time on a common GPU (ie. Titan Xp).
Note that MSRResNet represents modified SRResNet, please refer to  and the testing code for more details.

The top ranked participants in each track will be awarded and invited to follow the ICCV submission guide for workshops to describe their solution and to submit to the associated AIM workshop at ICCV 2019.
Note that for the final ranking and challenge winners we are weighing more the teams/participants with entries in more than one track challenge. Ideally each participant will have entries for all three tracks.
More details are found on the data section of the competition.
To learn more about each competition, to participate in the challenge, and to access the new dataset everybody is invited to register at the following links, accordingly:
The training data is already made available to the registered participants.
The evaluation consists from the comparison of the x4 super-resolved images with the ground truth images and the reporting of the number of parameters (memory) and inference time / runtime of the solution.
Only deep learned solutions working with PyTorch version 1.1.0 are sought. Other solutions will accepted but will not be officialy ranked.
For the Track 1 Parameters, Track 2 Inference, and Track 3 Fidelity we use the standard Peak Signal To Noise Ratio (PSNR) and, complementary, the Structural Similarity (SSIM) index as often employed in the literature, as well as the runtime obtained on a Nvidia Titan Xp GPU card. PSNR and SSIM implementations are found in most of the image processing toolboxes. For each dataset we report the average results over all the processed images belonging to it.
Note that we will rely on selfreported number of parameters and runtime / inference time in the validation phase, while for the final test phase ranking the challenge organizers will check and run the provided solutions and compute these measures for all 3 tracks.
For submitting the results, you need to follow these steps:
Runtime per image [s] : 0.170
Parameters : 1517571
Extra Data  / No Extra Data  : 1
Other description : Model name: MSRResNet; GPU: Titan Xp; Extra data: Flickr2K and OST
These are the official rules (terms and conditions) that guvern how the AIM challenge on real world super-resolution 2019 will operate. This challenge will be simply reffered to as the "challenge" or the "contest" throghout the remaining part of these rules and may be named as "AIM" or "DIV2K" benchmark, challenge, or contest, elsewhere (our webpage, our documentation, other publications).
In these rules, "we", "our", and "us" refer to the organizers (Kai Zhang (kai.zhang [at] vision.ee.ethz.ch), Shuhang Gu (shuhang.gu [at] vision.ee.ethz.ch) and Radu Timofte (Radu.Timofte [at] vision.ee.ethz.ch) from ETH Zurich, CVL) of AIM challenge and "you" and "yourself" refer to an eligible contest participant.
Note that these official rules can change during the contest until the start of the final phase. If at any point during the contest the registered participant considers that can not anymore meet the eligibility criteria or does not agree with the changes in the official terms and conditions then it is the responsability of the participant to send an email to the organizers such that to be removed from all the records. Once the contest is over no change is possible in the status of the registered participants and their entries.
This is a skill-based contest and chance plays no part in the determination of the winner (s).
The goal of the contest is to super-resolve an input image to an output image with a magnification factor x4 while the proposed solution is constrained on any two of the following aspects: number of parameters, inference time, fidelity (PSNR), and the challenge is called constrained super-resolution.
Focus of the contest: it will be made available DIV2K dataset adapted for the specific needs of the challenge. The images have a large diversity of contents. We will refer to this dataset, its partition, and related materials as DIV2K. The dataset is divided into training, validation and testing data. We focus on three distinct settings: (track 1: parameters) the aim is to lower the number of parameters of a deep super-resolution solution while maintaining or improving in terms of inference time and fidelity (PSNR) over MSRResNet (Ledig et al, 2017 & Wang et al, 2018), and (track 2: inference) the aim is to lower inference time while preserving or improving in terms of number of parameters and fidelity (PSNR) over MSRResNet, and (track 3: fidelity) the aim is to improve the fidelity (PSNR) while preserving or improving in terms of number of parameters and inference / runtime over MSRResNet. The participants will not have access to the ground truth images from the test data. For each track the ranking of the participants is according to the performance of their methods on the test data. The participants will provide descriptions of their methods, details on (run)time complexity, number of parameters and (extra) data used for modeling. The winners will be determined according to their entries, the reproducibility of the results and uploaded codes or executables, and the above mentioned criteria as judged by the organizers.
The registered participants will be notified by email if any changes are made to the schedule. The schedule is available on the AIM workshop web page and on the Overview of the Codalab competition.
