The kind of aliasing you deal with in digital photography happens when detail in the image, when projected onto the sensor is roughly the same size or smaller than a single pixel in the sensor. This can lead to Moire patterns and false color in the image.What is the meaning of alias?
noun, plural a·li·as·es. a false name used to conceal one's identity; an assumed name: The police files indicate that “Smith” is an alias for Simpson. at another time; in another place; in other circumstances; otherwise.Where does aliasing occur in audio?
Aliasing can occur in signals sampled in time, for instance digital audio, or the stroboscopic effect, and is referred to as temporal aliasing. It can also occur in spatially sampled signals (e.g. moiré patterns in digital images ); this type of aliasing is called spatial aliasing .What is aliasing and anti-aliasing?
Aliasing is the visual stair-stepping of edges that occurs in an image when the resolution is too low. Anti-aliasing is the smoothing of jagged edges in digital images by averaging the colors of the pixels at a boundary. The letter on the left is aliased. The letter on the right has had anti-aliasing applied to make the edges appear smoother.
