Robust Identification of Periodic Systems with Applications to Texture Inpainting.
Mario Sznaier, Octavia Camps · 2006
In this paper we address the problem of robust identification of discrete LTI systems that have a periodic impulse response. The main result of the paper shows that this problem can be solved by factoring a suitable defined Hankel operator. These results are illustrated with a practical example arising in the context of image processing: completing a textured image where some pixels are missing.
