5. Consider two images f(x,y) and g(x,y), with corresponding unnormalized histograms hy(ra) and Tk h(r). respectively. Thus h(r) gives the number of pixels having a value r in the image f(,y). Under what conditions can you determine the histogram of a new image f(a.y) +g(x.y) given only the histograms of the individual images to begin with? i.e., you are given only the histograms but not the images). 5.
