digital image processing

7.5 Consider an image that is black except for a single pixel wide stripe from the top left to the bottom right (Fig. E7.1, top left). Can you explain its Fourier transform (Fig. E7.1, bottom left)? Also, consider an image ofnoise (Fig. E7.1, top right), i.e. every pixel has a random value, independent of all other pixels. Can you explain its Fourier transform (Fig. E7.1, bottom right)? What does the bright spot in the middle of the noise Fourier transform image represent? Why does the Fourier transform of the noise appear dark gray? Fiure E Stripe and noise, and their Fouricr transforms. What is the result of performing a Fourier transform on the Fourier transform of an image? Try it out. Can you explain the result
