2 7 5+ -7 -5 5 7 -5 -7 (26 pts) (6 pts if empty) We have the shown DFT output for an image. There are only the 2 non-zero components indicated as red points. All other components are zero. Both red points are representing the complex number 12 5i. Assume that this transform can perfectly represent the image without any loss of information. You may leave your answers in in terms of acos, atan etc... a) Find the amplitudes and phases of 2D sinusoids that represent the underlying image. b) Find the orientation of those sinusoids in 2D (i.e. provide an angle)
