You can't blur a pixel, you need a set of pixels. The algorithm used is
somewhat similar, but the goal and result are different. Blurring
removes information from an image, spreading colors out across adjacent
pixels. Antialiasing adds data, coloring each pixel with the overall
color of the area it covers instead of a single point within that area,
and is not dependant on the colors of adjacent pixels. You can use an
antialiasing algorithm with a large image as input, but you will get a
smaller image as a result.
