Indeed\, much of the progress in image processing in the past few decades has been due to advances in the formulation and practice of regularization. This\, coupled with the progress in the areas of optimization and numerical analysis\, has yielded much improvement in computational methods of solving inverse imaging problems. \nIn this talk\, we will revisit a number of inverse problems including image registration (alignment)\, image inpainting (completion)\, super-resolution (resolution enhancement)\, and present some recent research ideas mainly aimed at medical imaging applications. Furthermore\, we present an approach based on deep convolutional neural networks to address two image restoration problems\, image inpainting and super-resolution.  The method applies our so-called “Edge-Connect”\, a two-stage adversarial model that contains an edge generator followed by an image completion network.  We evaluate the model and observe that it outperforms current state-of-the-art techniques quantitatively and qualitatively. \nDatos de contacto:\nMehran Ebrahimi\, PhD\nAssociate Professor\, Faculty of Science\nOntario Tech University\nOshawa\, Ontario\, Canada\ne-mail: mehran.ebrahimi@uoit.ca\nURL: http://www.ImagingLab.ca URL:https://canalugr.si2.dev/evento/conferencia-inverse-problems-in-image-processing/ LOCATION:CITIC-UGR\, Calle Periodista Rafael Gómez Montero\, nº 2 \, Granada\, Granada\, España CATEGORIES:Conferencias, seminarios, divulgación científica ATTACH;FMTTYPE=image/jpeg:https://canalugr.si2.dev/wp-content/uploads/2016/10/viñetacitic.ugr_.jpg GEO:37.1773363;-3.5985571 X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=CITIC-UGR Calle Periodista Rafael Gómez Montero nº 2 Granada Granada España;X-APPLE-RADIUS=500;X-TITLE=Calle Periodista Rafael Gómez Montero\, nº 2:geo:-3.5985571,37.1773363 END:VEVENT END:VCALENDAR
