I used the following codes f=imread('phalenges.jpg'); [M,N]=size(f); sig=10; F=fft2(f); H=lpfilter('gaussian',[M,N],'sig'); G=H.*F; g=real(ifft2(G)); imshow(g,[])
But following error message was displayed
??? Undefined function or method 'lpfilter' for input arguments of type 'char'.

you should download the lpfilter.m file from internet and put it your work directory to be able to use this function
