Solutions of fourth-order partial differential equations in a noise removal model. (English) Zbl 1138.35353
Summary: 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.
