NTIRE 2021 Challenge on Image Deblurring
This is an incremental challenge report for researchers in computer vision, focusing on image deblurring with combined artifacts.
The paper reviews the NTIRE 2021 Challenge on Image Deblurring, which tackled the problem of recovering clean images from blurry ones with joint artifacts like low resolution or JPEG compression, resulting in state-of-the-art performance from winning methods.
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.
