I did point out the the film in Star Trek's case. By re-imaging I would mean they largely retain the original character names and/or background in some form (even if we have a gender change of some characters in BSG and Five-O). The spin-oRAB are essentially new characters in new situations.
I don't count new Who as a re-imaging. More of an improvement on the production values of classic Who, and a continuation of the character's timeline.
