Error estimates for finite volume scheme for Perona-Malik equation
A. Handlovicova and Z. Kriva


Abstract.  We present Perona-Malik nonlinear image selective smoothing equation (modified in the sense of Catt\'e, Lions, Morel and Coll) which is investigated esspecially from numerical point of wiev. Error estimates in $L_{2}$ norms for fully discrete numerical finite volume scheme are derived and proved. Some numerical examples are presented.

Keywords: Perona Malik equation, image processing, finite volume method, error estimates.  

AMS Subject classification:  35K55, 65M12.
