Dear group, I have a question: I have used the standard command GeometricTransformation to let my students explore the geometrical effect of a linear transformation, please see the second half of this computer-lab work: http://homepage.cem.itesm.mx/lgomez/data/LAD02.pdf
. As you can see, I try using only standard Mathematica commands, without the "advanced" notation shortcuts like @ &, etc. My students did some similar work by hand before going to the lab.
Now, for our next lab session, I want my students to take an image of "The Ambassadors", by Holbein http://en.wikipedia.org/wiki/File:Holbe ... sadors.jpg
and then apply to the position of each pixel a linear transformation to generate an image similar to this one: http://commons.wikimedia.org/wiki/File: ... phosis.jpg
so that the hidden skull is clearly revealed. My problem is that I want them to do it with simple standard Mathematica commands (they are NOT students of engineering nor Math, their career is more Art-oriented), I would like to have something similar to the command GeometricTransformation, where they only enter the Image, the Matrix, and they get the result, if possible I do Not want them to use Mathematica commands to actually mutliply the matrix times each pixel position (they already have done that by hand in very very simple "images")
Do you have any suggestions?
