LULU operators for functions of continuous argument
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Roumen Anguelov Carl RohwerThe LULU operators, well known in the nonlinear multiresolution analysis of sequences, are extended to functions defined on a continuous domain, namely, a real interval. We show that the extended operators replicate the essential properties of their discrete counterparts. More... -
