Question

Complete this in matlab language. The routine takes a noisy image(in grayscale format of type uint8) as input and attempts to remove the noise with an arithmetic mean filter. A 3x3 window is used to filter the noisy image. The output image type should be uint8.

Code:

Function Im=arithmetic_mean_filter(NoisyIm,d)

%check if the noisy image is grayscale and of uint8

assert_grayscale_image(NoisyIm);

assert_uint8_image(NoisyIm);

%filter the noisy image with arithmetic mean filter. Using 3x3 window to filter the image

Im=?

Explanation / Answer

Function lm = airthmatic_mean_filter(Noisylm,d)
assert_grayscale_image(Noisylm);
assert_uint8_image(Noisylm);
  
Noisy = imread(Noisylm);
[r,c] = size(Noisy);
  
for i=2:r-1
for j=2:c-1
lm(i,j) = ceil(sum(sum(Noisy(i-1:i+1,j-1:j+1)))/9);
end
end
end
