CVPR 2018: Learning to See in the Dark
Why Hacker News recommends it
HN commenters flag it as a remarkable machine-learning result, notably for showing that training on raw images beats JPEG.
What it is
A short video accompanying the CVPR 2018 paper Learning to See in the Dark. It shows a neural network producing sharp images from very low-light raw sensor data, compared against denoising approaches.

Remarkable machine learning result for "producing astoundingly sharp photos in very low light" (Cory Doctorow - [LINK] ) Demo example (one of many examples - drag the middle slider from left-to-right): [LINK] GitHub: [LINK] Paper: [LINK] Video: [this video]

Public raw image datasets are rare, probably because most cameras, except DSLRs, don't support storing raw images. Also, the nature of the inference may not require high fidelity raw images since they're going to be down-sampled anyway. Unless research suggests that raw images improve inference metrics, nobody's going to invest effort into building a raw image dataset. One notable recent exception to this is the "Learning to see in the dark" paper on low light image enhancement[1] - they found that training on raw images gives much better enhancement than JPEG. The data availability problem may start getting solved in the near future because mobiles (atleast Android) support storing and proc

To me the results seem vastly superior to those sort of simple DSP algorithms. The video shows a comparison with some denoising: [this video]
