What is interpolation artifacts?

Interpolation artifacts are a consequence of the inability of the most commonly used interpolation algorithms to properly represent aliased linear features in geophysical images (e.g., minimum curvature, Briggs, 1974; bidirectional, Yao and Rokne, 1996; and kriging, Hansen, 1993).

What is an artifact in signal processing?

In natural science and signal processing, an artifact or artefact is any error in the perception or representation of any information introduced by the involved equipment or technique(s).
