I'm teaching myself computer graphics and am trying to figure out the difference in Reconstruction and Resampling. So say I have a 64 x 64 image that I want to:

1. Recreate at a 128 x 128 resolution


2. Recreate at the same 64 x 64 resolution


It seems by my understanding that with number 1 we will do reconstruction and resampling. Reconstruction is basically just the act of creating a new image from an existing image and the Resampling will be what we need to do to figure out what the new values will be since we will have double the pixels.

In number 2, I think all we are doing is reconstruction since each pixel will be a one to one ratio.


Any help in this would be great. I think I'm making this harder than what it needs to be.
