Cubic spline smoothing kernel
WebAccordingly, the term “cubic spline” is assigned to continuous cubic functions with second-order continuous derivatives and nodes that allow jumps of third-order derivatives. If the polynomial degree is b and the vector of the nodes is t , then the set of polynomial splines with s continuous derivatives forms a linear space. WebWe can apply the fast filtering scheme outlined previously for derivative reconstruction with the cubic B-spline's derivative. The only difference in this case is that now all the filter kernel weights sum up to zero instead of one: w i (x) = 0.Now, in comparison to Listing 20-1, where the two linear input samples were weighted using a single lerp(), we obtain the …
