PIRM: Perceptual Image Restoration and Manipulation workshop and challenges on image super-resolution, mobile photo enhancement and spectral reconstruction
in conjunction with ECCV 2018, Munich, Germany

SCOPE

A key goal in image restoration, manipulation and generation, is to produce images that are visually appealing to human observers. In recent years, there has been great interest as well as significant progress in perceptually-aware computer vision algorithms. However, many works have observed a fundamental disagreement between this recent leap in performance, as evaluated by human observers, and the objective assessment of these methods by common evaluation metrics (e.g. PSNR, SSIM). This workshop will revolve around two main themes: (i) How to design algorithms which satisfy human observers, and (ii) How to evaluate the perceptual quality of such algorithms.


CHALLENGES

The PIRM challenges will promote perceptual image restoration. State-of-the-art methods in terms of perceptual quality (e.g. SRGAN) are rated poorly by "simple" distortion measures such as PSNR and SSIM. Therefore, in contrast to previous challenges, the evaluation and ranking will be done in a perceptual-quality aware manner based on [Blau and Michaeli, CVPR'18]. This unified approach quantifies the accuracy and perceptual quality of algorithms jointly, and will enable perceptual-driven methods to compete alongside algorithms that target PSNR maximization.

CALL FOR PAPERS

Challenge participants may submit papers for publication at PIRM 2018 workshop and also with the ECCV 2018 Workshop proceedings. The papers should comply with the ECCV 2018 guidelines. Papers will be accepted based on: (i) academic quality, and (ii) challenge ranking.
The submission site will be made available soon.


CALL FOR POSTERS

A poster session will be held at the workshop. We invite submissions of posters presenting work on perceptual-quality driven algorithms, methods for evaluating perceptual quality, or any other related topic.

To submit your poster, please send an extended abstract of 2-3 pages (ECCV 2018 paper template) by email to posters@pirm2018.org. The email must include the poster title, authors, affiliations, and main contact email. Submission deadline is July 29th.

Submissions will be reviewed by the workshop organizers. Accepted posters will be presented at the workshop. Note that accepted abstracts will not appear in the ECCV workshop proceedings.
