To) s Tr) A/2 B/2 Lo 0 4. Suppose images fxy) and g(x.y) have histograms hy and h Suppose you form image k(x,y) as the sum of these two images: k(x.y) -f(x,y)+gx,y) (a) Under what conditions (on images f and g) can you determine the histogram hk of image k in terms of the histograms hy and h? That is, under what conditions can you determine h if you are only given h and hg? Hint: this turns out to be fairly restrictive.) b) Explain how you would derive h in this case.
