Radon transform computation. (20%) (a) Show that the Radon transform of the unit impulse 8(x, y) is a straight vertical line in the po-plane passing through the origin, i.e., (10%) if p = 0 g(0,0) = { otherwise. (b) Show that the Radon transform of the impulse 8(x-xo, y-yo) is a sinusoidal curve in the p0-plane. (10%)
