“…The B-spline B i,d,s can be expressed as a concatenation of d + 1 successive polynomials pieces of degree d. It is equal to 0 outside the segment [11] that keeps a very short support when d increases. [11] (bottom) with uniform segmentation.…”

“…Therefore it can be interesting to use piecewise models to decrease the number of necessary coefficients. Naraharisetti et al [11], [55] have reformulated the model in a more general form that is expressed for z i with i = 1 or 2 as:…”
