We propose a time evolution model for total‐variation based blind deconvolution consisting of two evolution equations evolving the signal by means of a nonlinear scale space method and the kernel by using a diffusion equation starting from the zero signal and a delta function respectively. A preliminary numerical test consisting of blind deconvolution of a noiseless blurred image is presented. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
