Define anti-aliasing
What do you understand by the term anti-aliasing? Describe briefly?
Expert
Anti-aliasing is a technique for enhancing the realism of an image by eliminating the jagged edges from it. Such jagged edges or jaggies appear as a computer monitor has square pixels, and such square pixels are inadequate for exhibiting lines or curves which are not parallel to the pixels and other reason is low sampling rate of the image information, which in turn leads to such jaggies.
Negative feedback principle: It is the idea that in a system where there are self-propagating situations, those new situations tend to act against formerly existing situations. Such a principle is in actuality a restatement of the conservation law.
