Raw burst denoising in the HDR+ pipeline
vendredi 18 juin 2021, 16h00 - 17h00
HDR+ is an image processing pipeline presented by Google in 2016. At its core lies a denoising algorithm that uses a burst of raw images to produce a single higher quality image. Since it is designed as a versatile solution for smartphone cameras, it does not necessarily aim for the maximization of standard denoising metrics, but rather for the production of natural, visually pleasing images. In this presentation, we will discuss and analyze the HDR+ burst denoising algorithm architecture and the impact of its various parameters. We will also take a few minutes to showcase the result of our open source implementation of the algorithm through an interactive demo.
