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.
