I don't see how any choice of a function g(theta) could have the property they desire, ie could eliminate R(g(theta)). Can anyone explain?

- sanxiyn 9y agoIt's expressed somewhat awkwardly, but what's going on is that R(x) is zero if x is in range of g, and infinite otherwise. Choice of g is such that natural images are in range of g, and non-natural images aren't.
- tgb 9y agoSorry I still don't understand. They require g to be surjective. Edit: in their paper they call it f_theta and it's explicitly not surjective. Dunno why their writeup is so confused.
