Talk Karen Egiazarian
Le Prof. Karen Egiazarian, CEO, Noiseless Imaging Oy (Finland), donnera un talk intitulé:
GPU-friendly Image Denoising
Date: Vendredi 7 décembre 2018 à 14h15
Lieu: CUI / Battelle bâtiment D, Amphithéâtre
This talk is about modelling and estimation of real camera noise and methods of noise suppression. We give a short overview of non-learning based methods, which utilize sparsity and self-similarity image priors, as well as learning based methods, in particular, convolutional neural network based ones. Next, we describe a new class of hybrid image denoisers: NN3D. They outperform counterparts, combine advantages of BM3D and DnCNN based denoisers, and provide superior quality of restored images.
Karen O. Egiazarian (Eguiazarian) (Senior Member IEEE, 1996) received M.Sc. in mathematics from Yerevan State University, Armenia, in 1981, the Ph.D. degree in physics and mathematics from Moscow State University, Russia, in 1986, and a Doctor of Technology from Tampere University of Technology, Finland, in 1994.
