Video transformation
If you're asking whether you can use AE to increase the actual or apparent resolution of a low-res source, the answer is no. You can't create resolution where none exists. If you could, no one would ever spend money on hi-res cameras. 

What you can do is 'sharpen' an image, which increases the contrast of edge detail and may increase apparent resolution a little bit. But this doesn't increase actual resolution; it actually reduces it slightly.
