Implement gaussian$\_$filter.m$,$ use hsize $=5,$ sigma $=2,$ and save the image as gaussian$\_5.$jpg

Please do this in MatLab using the pseudocode below. $$Gaussian Filter$$ needs to be used.

PLEASE DO NOT USE IN$-$BUILT MATLAB FUNCTIONS SUCH AS $$imfilter$()$

guassian$\_$filter.m

function output $=$ gaussian$\_$filter$($img$,$ hsize, sigma$)$

H $=$ fspecial$(\text{'}$gaussian$\text{'},$ hsize, sigma$)$;

$\%$ YOUR CODE HERE

end

$\%\%$ Gaussian filter

hsize $=5$; sigma $=2$;

img$\_$gaussian $=$ gaussian$\_$filter$($img$,$ hsize, sigma$)$;

figure, imshow$($img$\_$gaussian$)$;

imwrite$($img$\_$gaussian, 'gaussian$\_5.$jpg$\text{'})$;
