Write code in MATLAB Use any portrait head photo. Use photo manipulation to get gray scale image: you may use any matrix size, such as 512 times 512: you may use integer to represent gray scale. Write a matlab code to read the image, apply Fourier transformation to generate a k-space complex image of your face with frequency range [-k_max, k_max] in both kx and ky axes. Then,| Null the data inside [-k_max, /4, k_max/4] along both axes in k-space, ie, set k-space signal values inside the central square [-k_max/4, k_max/4] to zero. Then inverse Fourier transform back to image space
