5 x 5 median filter with out inbuilt function

I am required to use just median() not medfilt2()

Please help with the code

%% 2. Median Filter
sad1=imread('sadimg.bmp');                                  %a) Read ‘sadimg.bmp’ store image into ‘sad1’ 

median_filt=;                                               %b) Make a function ‘median_filt’ 
 
re_sad1=;                                                   %c) Using ‘medain_filt’, Apply 5x5 median filter to ‘sad1’store result ‘re_sad1’

I think it wants you do use a double for loop:

[rows, columns] = size(sad1);
re_sad = .....
for col = 1 : columns
    for row = 1 : rows
        subImage = ..........
        re_sad(row, col) = med(.............
    end
    
end

You need to get a 5x5 subimage at each location and then take the median of that. Here's a hint:

data = randi(99, 6, 6) % Create sample data
subMatrix = data(2:5, 3:4) % Extract a submatrix

data =

69 76 71 12 75 55

32 79 75 50 26 14

95 19 28 96 51 15

4 49 68 34 70 26

44 45 65 58 89 84

38 64 17 23 95 26

subMatrix =

75 50

28 96

68 34

65 58
