2.21 A motion-blurred image (uniform motion in the x-direction with x0(t) ¼ a tT

) is observed in the presence of additive white noise with a power spectrum of Sn(vx, vy) ¼ N0.

a. What is the transfer function of the Wiener filter in terms of the power spectrum of the image?

b. Give an algorithm for FFT implementation of the Wiener filter
