Unformatted text preview: (image – not the power spectrum) will be for a sufficiently large value of K ? (What is the result?) b. Derive an expression for the minimum value of K that will guarantee the result in part (a). The second set of three problems is: 1. Suppose that a digital image is subjected to histogram equalization. Show that a second pass of histogram equalization (on a histogram-equalized image) will produce exactly the same result as the first pass. 2. Two images, f(x,y) and g(x,y) , have histograms h f and h g . Give conditions under which you can determine the histograms of a. f(x,y) + g(x,y) b. f(x,y) – g(x,y) 3. Discuss the limiting effect of repeatedly applying a 3 x 3 lowpass (averaging) spatial filter to a digital image. Ignore the border effects. (Compare with problem 3 in the first set, remembering that not the same filter is used here.)...
