In most computer graphic design, when detailed images are drawn at the pixel-level the pixels are blurred with those next to them to make the border look more natural and less pixelated. I know in some things such as text rendering this is called 'anti-aliasing', you can see an example of what I'm talking about in one of the first diagrams on the Wikipedia article.
The term 'anti-aliasing' and 'aliasing' seems to refer to more than just blurring pixels to produce a more realistic image though.
In the game Lethal League, this technique is not used so as to give the graphics an interesting aesthetic, where the art seems particularly pixelated even though the pixels are no bigger than normal (you can see what I mean here on the Lethal League website)
So, is there a name for this technique used to make lines look more like lines and borders look less pixelated etc.? I don't think 'anti-aliasing' is the term I'm looking for as sometimes it's not used to avoid an 'alias', as seen in the Lethal League art where it is specifically avoided to produce a specific aesthetic.
You would use the word like "Most images are/use [word] to make them look less pixelated" or "Some graphic designers avoid using [word] to create a pixel-art aesthetic" or something like that.
Just to clarify why I didn't want to use the term anti-aliasing: this term is used for the removal of aliasing, where the jagged edges are an unintentional and unfaithful representation of what you are trying to make an image of. This is why I gave the Lethal League example, there's no aliasing there as it's an intentional aesthetic. So the real question I was trying to ask is that if someone were to blur the lines on a piece of pixel art to make it more realistic, what would that be called? It's not anti-aliasing as the pixelisation was intentional, aliasing is caused by the computer attempting to pixelise something that's not pixelised. I'm simply looking for the word to describe blurring the lines rather than removing computer-generated unwanted aliasing.
