Abstract
This correspondence presents results concerning the display of interpolated images for cosmetically pleasing effects. Replication, bilinear interpolation, and various cubic spline function interpolators are investigated as to numeric computational difficulty and psychovisually pleasing results. A degree of freedom analysis is provided to demonstrate the fact that apparent image improvement does not necessarily increase the inherent quantitative information within an image.
