Hi François,
Wow! I don't need those, but it is very impressive if you have
implemented those algorithms!
What I am hoping to do is simply throw away every other line and
construct a new image only consisting of every other line.
I wonder if there is a way to use some kind of crude "nearest
neighbor" resizing method where I can resize to 50%, that will not
blend the lines but just throw away every other one.
if you have Photoshop (or an app that accepts photoshop plugins), you
may have a look at a very elementary filtering+subsampling series of
exercices at
http://cas.ensmp.fr/~chaplais/Photoshop_Wavelet_Workout/index.html
The programming is based is based on adobe's filter factory, and allows
you to experiment on image processing within photoshop with a very
simple yet effective programming language.
To come back to Rev, I just discovered that Rev had a "Raw" description
of images. If I have the time, I will implement the photoshop exercise
in Rev. The idea is to provide a free demonstration (i.e., it does not
require Matlab or Photoshop...) Ah!! time.....
Best,
