Weak-signal extraction enabled by deep-neural-network denoising of diffraction data
Jens Oppliger, M. Michael Denner, Julia Küspert +20
Removal or cancellation of noise has wide-spread applications for imaging and acoustics. In every-day-life applications, denoising may even include generative aspects, which are un…
