Query: NTIRE 2021 Challenge on Image Deblurring   Motion blur is a common photography artifact in dynamic environments that
typically comes jointly with the other types of degradation. This paper reviews
the NTIRE 2021 Challenge on Image Deblurring. In this challenge report, we
describe the challenge specifics and the evaluation results from the 2
competition tracks with the proposed solutions. While both the tracks aim to
recover a high-quality clean image from a blurry image, different artifacts are
jointly involved. In track 1, the blurry images are in a low resolution while
track 2 images are compressed in JPEG format. In each competition, there were
338 and 238 registered participants and in the final testing phase, 18 and 17
teams competed. The winning methods demonstrate the state-of-the-art
performance on the image deblurring task with the jointly combined artifacts.
