NTIRE 2019

New Trends in Image Restoration and Enhancement workshop

and challenges on image and video enhancement, and quality assessment

in conjunction with CVPR 2019

Sponsors (TBD)

Call for papers

Image restoration and image enhancement are 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 restoration or enhancement 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.

This workshop builds upon the success of the previous NTIRE editions: at CVPR 2017 and 2018 and at ACCV 2016 . Moreover, it relies on all the people associated with the NTIRE past events such as organizers, PC members, distinguished speakers, authors of published paper, challenge participants and winning teams.

Papers addressing topics related to image restoration and enhancement are invited. The topics include, but are not limited to:

  • Image/video inpainting
  • Image/video deblurring
  • Image/video denoising
  • Image/video upsampling and super-resolution
  • Image/video filtering
  • Image/video dehazing
  • Demosaicing
  • Image/video compression
  • Artifact removal
  • Image/video enhancement: brightening, color adjustment, sharpening, etc.
  • Style transfer
  • Image/video generation and hallucination
  • Image/video quality assessment
  • Hyperspectral imaging
  • Underwater imaging
  • Aerial and satellite imaging
  • Methods robust to changing weather conditions / adverse outdoor conditions
  • Perceptual enhancement
  • Studies and applications of the above.

NTIRE 2019 has the following associated groups of challenges:

  • image restoration and enhancement challenges
  • video restoration and enhancement challenges

The authors of the top methods in each category will be invited to submit papers to NTIRE 2019 workshop.

The authors of the top methods will co-author the challenge reports.

The accepted NTIRE workshop papers will be published under the book title "The IEEE Conference on Computer Vision and Pattern Recognition (CVPR) Workshops" by

Computer Vision Foundation Open Access and IEEE Xplore Digital Library
