[visionlist] Challenge on image super-resolution at NTIRE workshop @ CVPR 2017 (+2 weeks extension)

Apologies for multiple copies******************************New Trends in Image Restoration and Enhancement Challenge on Example-based Single-Image Super-Resolutionhttp://www.vision.ee.ethz.ch/nvia CodaLab platform.http://ift.tt/2ng82cd organizes two parallel challenge tracks on Example-based Single-Image Super-Resolution=Track 1: `bicubic’ downscaling (Matlab imresize)  – a commonly employed setup in the literature.

The `bicubic’ setup allows for easy deployment of the recent published super-resolution methods.
=Track
2: `unknown’ downgrading operators – but with available train data of
low and high res corresponding images. The `unknown’ setup constrains
the participants to work with the provided train data and to develop
robust solutions to learn from a limited set of examples.
The challenge aims to gauge the state-of-the-art, to compare and to promote different solutions with the new DIV2K dataset.=DIV2K
– a newly collected dataset of DIVerse 2K resolution images
(2048x[unspecified] pixel images) will be released with the NTIRE
challenge. DIV2K dataset is divided into 80%/10%/10% for
train/validation/test, resp.

For each track the low res
images are generated and provided to the registered participants for x2,
x3, and x4 downscaling factors.

Details about NTIRE challenge and links to its 6 competitions (2 tracks X 3 downscaling factors) can be found below:  http://ift.tt/2lf5yXH
