Image Processing: Mathematics, Engineering, or Art?

From the strict mathematical viewpoint, it is impossible to fully achieve the goal of digital image processing, which ].sto determine an unknown function of two dimensions from a finite number of discrete measurements Linearly related to it. However, the necessity to display image data in a form that is visually useful to an observer s~persedee such mathematically correct admonitions. Engineering defines the technological limits of what kind of image processing can be dorie and how the resulting image can be dieplayed. The appeal and usefulneea of the final image to the human eye pertains Effective to aesthetics. imago processing necessitates unification of mathematical theory, practical implementation, and artistic display.
