I would like to know wether there is a function in ITK library for spline smoothing, working the same way matlab’s “csaps” does, specifically under csaps(x,y,p,[ ],w) syntax (weighted smoothing, complex number input/output , etc, see https://www.mathworks.com/help/curvefit/csaps.html) . Thank you!
Welcome to ITK!
Yes, of interest are the classes:
More information can be found in the corresponding Insight Journal articles:

Hope this helps,
