A. Ghanbari Talouki; M. Majdi

Volume 8, Issue 4 , Autumn 2019, Pages 325-338

http://dx.doi.org/10.22105/riej.2020.215689.1116

Abstract
  Inpainting or completion is used with the purpose of restoring damaged images and video frames. This paper proposes an applicable algorithm to inpaint corrupted subjects in video frames. To begin with, background and foreground (moving subject) are separated from each other in each frame, with the aim ...  Read More
