The B-spline channel representation: Channel algebra and channel based diffusion filtering

By Michael Felsberg, Hanno Scharr, Per-erik Forssén, M. Felsberg, H. Scharr and P. -e. Forssén


In this paper we consider the channel representation based upon quadratic Bsplines from a statistical point of view. Interpreting the channel representation as a kernel method for estimating probability density functions, we establish a channel algebra which allows to perform basic algebraic operations on measurements directly in the channel representation. Furthermore, as a central point, we identify the smoothing of channel values with a robust estimator, or equivalently, a diffusio
