Solutions of fourth-order partial differential equations in a noise removal model. <i>Electronic Journal of Differential Equations, 2007</i>(120), pp. 1-11.1072-6691https://hdl.handle.net/10877/14335In this paper, we discuss the existence and uniqueness of weak solutions for a fourth-order partial differential equation stemmed from image processing for noise removal. We also present some numerical tests for high order filters.Text11 pages1 file (.pdf)enAttribution 4.0 InternationalExistenceUniquenessFourth-orderNoise removalArticle
