Smoothing spline — The smoothing spline is a method of smoothing, or fitting a smooth curve to a set of noisy observations.DefinitionLet (x i,Y i); i=1,dots,n be a sequence of observations, modeled by the relation E(Y i) = mu(x i). The smoothing spline estimate… … Wikipedia
Smooth operator — or smoothing operator may refer to:* Smooth Operator (song), a song by Sade * A smoothing operator, used to remove noise from data * A mathematical operator which is a smooth function, i.e., infinitely differentiable * Smoothie and juice bars… … Wikipedia
Edge preserving smoothing — is an image processing technique where the edge information is preserved during the smoothing process. It uses non linear operator which is able to remove texture and noise, while keeping edges and corners. The technique is known also as edge and … Wikipedia
