What is the difference between antialiasing and blurring? Is there a way to be more precise with antialiasing rather than going to filters/enhance/antialias a certain amount of times? like with gaussian blur you can put in the number for blurring radius.

I am asking this because I have been blurring my images but they sometimes get too blurry. I'm trying to blur or antialias the image below



OR



Any thoughts??

Blurring blurs all or a selected area of the images pixels.
Anti aliasing however, adjusts the pixels on the edge of the pixels area, so they do not stop abruptly, but gradually.
This causes the edges to look sharper.(not jagged)

Aliasing : when an object's edges are not blended at all, and is visibly pixelated, it is known as aliasing
Anti aliasing would be the opposite of that effect.

If you are trying to sharpen your images try Filters/Enhance/Unsharp mask
