What is the name of the phenomenon that corrupts the sampled image, and how does it happen?
(a) Shannon sampling, if the band-limited functions are undersampled
(b) Shannon sampling, if the band-limited functions are oversampled
(c) Aliasing, if the band-limited functions are undersampled
(d) Aliasing, if the band-limited functions are oversampled
The question was asked in unit test.
This interesting question is from Spatial and Gray-Level Resolution and Aliasing in portion Image Enhancement of Digital Image Processing
