The 4th edition of NTIRE: New Trends in Image Restoration and Enhancement workshop will be held June 17, 2019 in conjunction with CVPR 2019 in Long Beach, California.
Image restoration and image enhancement are key computer vision tasks, aiming at the restoration of degraded image content or the filling in of missing information. 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, with image restoration or enhancement serving 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. The emergence and ubiquitous use of mobile and wearable devices offer another fertile ground for additional applications and faster methods.
NTIRE 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 NTIRE workshop we have an NTIRE challenge on real image denoising. The challenge has two tracks.
Track 1: "Raw-RGB" focuses on denoising real noisy images in raw-RGB space (i.e., the camera sensor space).
Track 2: "sRGB" focuses on denoising real noisy images in the standard RGB (sRGB) space.
The top ranked participants on each track will be awarded and invited to follow the CVPR submission guide for workshops to describe their solution and to submit to the associated NTIRE workshop at CVPR 2019.
Note that for the final ranking and challenge winners we are weighing more the teams/participants with entries in more than one track.
To learn more about each competition, to participate in the challenge, and to access the 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 restored clean (denoised) images with the ground truth images. For this 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. We report the average results over all image blocks provided.
For submitting the results, you need to follow these steps:
Runtime per mega pixel [s] : 2.89
CPU / GPU : 1
Use of Metadata  / No use of metadata  : 1
Other: any further information about your method
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.
These are the official rules (terms and conditions) that guvern how the NTIRE challenge on real image denoising 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 "NTIRE Denoising" or "Denoising" benchmark, challenge, or contest, elsewhere (our webpage, our documentation, other publications).
In these rules, "we", "our", and "us" refer to the organizers (Abdelrahman Abdelhamed and Michael S. Brown, York University and Radu Timofte, ETH Zurich) of NTIRE 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 (kamel [at] eecs.yorku.ca 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.
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 restoration of a clean haze-free image from a hazy input image and the challenge is called ground truth-based single-image dehazing.
Focus of the contest: it will be made available a large dataset, subset of Smartphone Image Denoising Dataset (SIDD): ? pairs of images (noisy and ground-truth noise-free images). We will refer to this dataset, its partition, and related materials as SIDD dataset. The dataset is divided into training, validation and testing data. The goal is to restore the clean, noise-free image contents from noisy real images captured with a smartphone camera. The participants will not have access to the ground truth noise-free images from the test data. 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 the use of metadata information, the (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.
The registered participants will be notified by email if any changes are made to the schedule.
You are eligible to register and compete in this contest only if you meet all the following requirements:
This contest is void wherever it is prohibited by law.
Entries submitted but not qualified to enter the contest, it is considered voluntary and for any entry you submit NTIRE reserves the right to evaluate it for scientific purposes, however under no circumstances will such entries qualify for sponsored prizes. If you are an employee, affiliated with or representant of any of the NTIRE challenge sponsors then you are allowed to enter in the contest and get ranked, however, if you will rank among the winners with eligible entries you will receive only a diploma award and none of the sponsored money, GPU or travel grants.
NOTE: industry and research labs are allowed to submit entries and to compete in both validation phase and final test phase. However, in order to get officially ranked on the final test leaderboard and to be eligible for awards the reproducibility of the results is a must and, therefore, the participants need to make available and submit their codes or executables. All the top entries will be checked for reproducibility and marked accordingly.
We will have 3 categories of entries in the final test ranking:
1) checked with publicly released codes
2) checked with publicly released executable
3) unchecked (with or without released codes or executables)
In order to be eligible for judging an entry must meet all the following requirements:
Entry contents: the participants are required to submit image results and (code or executable). To be eligible for prizes, the top ranking participants should publicly release their codes or executables under a license of their choice, taken among popular OSI-approved licenses (http://opensource.org/licenses) and make their code or executables online accessible for a period of not less than one year following the end of the challenge (applies only for top three ranked participants of the competition). To enter the final ranking the participants will need to fill out a survey (fact sheet) briefly describing their method. All the participants are also invited (not mandatory) to submit a paper for peer-reviewing and publication at the NTIRE workshop and challenges (to be held on June 16, 2019, Long Beach, California).
