Implement median$\_$filter.m for lena$\_$noisy.jpg$,$ use patch size $=5$ and save the image as median$\_1.$jpg

Please do this in Matlab. Implement median$\_$filter.m function. Linear Filtering may be required. DO NOT USE INBUILT FUNCTIONS SUCH AS "imrotate$()"$

Lab$02.$m

img $=$ im$2$double$($imread$($lena$\_$noisy.jpg$))$;

$\%\%$ Median filter

patch$\_$size $=[5,5]$;

img$\_$median $=$ median$\_$filter$($img$,$ patch$\_$size$)$;

imwrite$($img$\_$median, $$median$.$jpg$)$;

median$\_$filter.m

function output $=$ median$\_$filter$($img$,$ patch$\_$size$)$
