A note on cubic convolution interpolation
Erik H. W. Meijering, Michael A. Unser · IEEE Transactions on Image Processing · 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.
