  This paper reviews the NTIRE2021 challenge on burst super-resolution. Given a
RAW noisy burst as input, the task in the challenge was to generate a clean RGB
image with 4 times higher resolution. The challenge contained two tracks; Track
1 evaluating on synthetically generated data, and Track 2 using real-world
bursts from mobile camera. In the final testing phase, 6 teams submitted
results using a diverse set of solutions. The top-performing methods set a new
state-of-the-art for the burst super-resolution task.
