A correspondent asked me to look into the implementation of bicubic image resampling algorithms, and is wondering how to deal with edges. Since the bicubic methods rely on a number of neighboring pixels, some method must be used to ‘fake’ the data along the edges.

Bucubic spine interpolation is "the method" used to fill data gaps. Depending on specific spline you get different interpolation. Are you looking for implementation details?
