Challenge overview

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 example-based RAW to RGB mapping, that is, the task of mapping an input RAW image to an output RGB image based on a set of prior examples of input-output images. The challenge has two tracks.

Track 1: "Fidelity", the target is to obtain an output image with the highest pixel fidelity to the ground truth as measured by PSNR.

Track 2: "Perceptual", the target is to achieve an output image with the best perceptual quality similar to the ground truth output image, as measure by Mean Opinion Score (MOS).

 

 

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 both tracks.

More details are found on the data section of the competition.

Competitions

To learn more about each competition, to participate in the challenge, and to access the newly collected ZRR dataset with RAW and RGB image pairs everybody is invited to register at the following links, accordingly:

The training data is already made available to the registered participants.

Provided Resources

  • Scripts: With the dataset the organizers will provide scripts to facilitate the reproducibility of the images and performance evaluation results after the validation server is online. More information is provided on the data page.
  • Contact: You can use the forum on the data description page (highly recommended!) or directly contact the challenge organizers by email (Andrey [at] vision.ee.ethz.ch and Radu.Timofte [at] vision.ee.ethz.ch) if you have doubts or any question.

Evaluation

The evaluation consists from the comparison of the synthesized RGB images with the ground truth RGB images.

For the Track 1 Fidelity we use the standard Peak Signal To Noise Ratio (PSNR) and, complementary, the Structural Similarity (SSIM) index as often employed in the literature. 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.

For the Track 2 Perceptual we use the Mean Opinion Score (MOS). However, since MOS requires opinions from human subjects it will be conducted only on the final test images, for the final ranking. Meanwhile, we will report the standard Peak Signal To Noise Ratio (PSNR) and the Structural Similarity (SSIM) index as often employed in the literature. 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.

For submitting the results, you need to follow these steps:

  1. process the input RAW images and keep the same name for the RGB image results as produced by your method (example: for an input file with name "083.png" the output file should be "083.png") 
    Note that the output RGB images should be saved with lossless compression and should have the pixel size of the input RAW images.
  2. create a ZIP archive containing all the RGB image results named as above and a readme.txt Note that the archive should not include folders, all the images/files should be in the root of the archive.
  3. the readme.txt file should contain the following lines filled in with the runtime per image (in seconds) of the solution, 1 or 0 accordingly if employs CPU or GPU at runtime, and 1 or 0 if employs extra data for training the models or not.
    runtime per image [s] : 10.43 
    CPU[1] / GPU[0] : 1
    Extra Data [1] / No Extra Data [0] : 1
    Other description : Solution based on A+ of Timofte et al. ACCV 2014. We have a Matlab/C++ implementation, and report single core CPU runtime. The method was trained on Train 91 of Yang et al. and BSDS 200 of the Berkeley segmentation dataset. 
     The last part of the file can have any description you want about the code producing the provided results (dependencies, link, scripts, etc.)
    The provided information is very important both during the validation period when different teams can compare their results / solutions but also for establishing the final ranking of the teams and their methods.

Advances in Image Manipulation (AIM) challenge on example-based RAW to RGB mapping @ ICCV 2019

 

Example-based RAW to RGB Mapping Challenge

These are the official rules (terms and conditions) that guvern how the AIM challenge on example-based RAW to RGB mapping 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 "ZRR" benchmark, challenge, or contest, elsewhere (our webpage, our documentation, other publications).

In these rules, "we", "our", and "us" refer to the organizers (Radu Timofte and Andrey Ignatov 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 (Andrey [at] vision.ee.ethz.ch and Radu.Timofte [at] vision.ee.ethz.ch) 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.

1. Contest description

This is a skill-based contest and chance plays no part in the determination of the winner (s).

The goal of the contest is the mapping of an input RAW image to an output RGB image and the challenge is called example-based RAW to RGB mapping.

Focus of the contest: it will be made available a newly collected dataset of at least 90000 newly collected image pairs 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 ZRR (Zurich-area collected RAW and RGB paired images dataset). The dataset is divided into training, validation and testing data. We focus on two distinct settings: (track 1: fidelity) example-based RAW to RGB mapping where the target is the fidelity of the output image results to the ground truth images, and (track 2: perceptual) example-based RAW to RGB mapping where the target is to achieve output images with the same perceptual quality of the reference ground truth images. 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 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.

2. Tentative contest schedule
