hi
i need to make
"To perform the blurring process on Pear a rotationally symmetric Gaussian lowpass filter of size 20 with standard deviation 10 is used. One object in each image is blurred"
and this code i made it but doesnt work

%n= imread('peppers.png');
%H = fspecial('disk',5);
%blu = imfilter(n,H,'replicate');
%k=rgb2gray(blu);
%imwrite(im2uint8(k),'H:\Animals\a51.jpg');

i need image have tow object one is focue and other not or
the left side is blurring and the right is not plzzzzzzzzzz help

in matlab this code works:


n= imread('pulverulenta_grayscale.jpg');
H = fspecial('disk',5);
blu = imfilter(n,H,'replicate');
imshow(blu);


make sure that gaussian low pass filter works for just garscale image.
if you have color image then first convert it into grayscale by using rgb2gray
