The narrowing domain gap between real and synthetic imagery makes it possible to use CG images as training data for deep learning models targeting high-level computer vision tasks, such as autonomous driving and semantic segmentation.
Training nightmode ISP networks relies on large-scale datasets of image pairs with: (1) a noisy raw image captured with a short exposure and a high ISO gain; and (2) a ground truth low-noise raw image captured with a long exposure and low ISO that has been rendered through the ISP.
In this paper, we leverage the availability of these two cameras for the task of illumination estimation using a small neural network to perform the illumination prediction.
Because of this, a number of methods have been proposed to "unprocess" nonlinear images back to a raw-RGB state.

This challenge is based on a newly collected validation and testing image datasets, and hence, named SIDD+.
Modeling and synthesizing image noise is an important aspect in many computer vision applications.
Ranked #8 on Image Denoising on SID x300
We propose a systematic procedure for estimating ground truth for noisy images that can be used to benchmark denoising performance for smartphone cameras.
Gender classification aims at recognizing a person's gender.
Existing methods attempt to estimate a spatially varying illumination map, however, results are error prone and the resulting illumination maps are too low-resolution to be used for proper spatially varying white-balance correction.
