Hello every one..

I am confused on a one question of my assignment which is on fourier transformation.Can anyone help me plz?The question is

1) Use lena image (f(i,j)). Calculate F(u-N/2,v-N/2). Plot|F(u-N/2,v-N/2)|. Reverse the magnitude of FT properly so that the resultant image is not too dark.

I am waiting for this answer. Can any one here o help me with a complete code? Thanks
