Time-delayed Perona-Malik type problems
H. Amann


Abstract.  We propose time regularizations for ill posed evolution equations of the type of the Perona-Malik equation of image processing, prove that they are well posed, and give numerical evidence for their superiority to the widely used space regularizations.

Keywords: Image processing, regularization of backward parabolic problems.
