how to do low pass filtering of an image in frequency domain

[prashiit]

hii..

   I have to implement low pass filter in frequency domain for an image. I have converted the image into frequency domain using IMAQ frequency domain pallete. Now, for low pass filter I have to calculate the distance between the center of frequency domain and every point in frequency domain. How can I do low pass filtering of image in frequency domain

Thanks
