A Note on Cubic Convolution Interpolation

E. Meijering, M. Unser

IEEE Transactions on Image Processing, vol. 12, no. 4, pp. 477-479, April 2003.



We establish a link between classical osculatory interpolation and modern convolution-based interpolation and use it to show that two well-known cubic convolution schemes are formally equivalent to two osculatory interpolation schemes proposed in the actuarial literature about a century ago. We also discuss computational differences and give examples of other cubic interpolation schemes not previously studied in signal and image processing.
