Viewpoint dependant deformation of objects in photos I have a question concerning the deformation of objects in photos. Which deformations can an object depicted on a photo undergo through viewpoint and condition changes?

Some deformations I have in mind are:


rotation
scale
shearing
translation
illumination
occlusion


Which deformations did I forget?

Best!
Since you have listed "illumination", I am assuming that "condition changes" include changes in lighting.  So I would add cast shadows, which will change if you move the light source.

Also, all the geometric transformations you have listed are affine. But if you move the camera perspective changes as well. So you may want to consider the projective transformation.
