MATLAB: Divide group into subgroups

groupssubgroups

I have a matrix 5×5 and i managed from this matrix to create a matrix 5×10 by creating a subgroup of 2 in each column.

So Matrix =

0 0 0 1 0 0 0 0 0 0
1 0 0 0 0 0 0 0 0 0
0 0 1 0 0 0 0 0 0 0
0 0 0 0 0 1 0 0 0 0
0 0 0 0 0 0 0 0 0 1

I want to tell that row 1 belongs to group 2, row 2 belongs to group 1, row 3 belongs to group 2, row 4 belongs to group 3 and row 5 belongs to group 5!

Thank you so much

group=[2 1 2 3 5]

the variable group indicate what you want

Use the same method as in your previous question except now use the height of the bounding box instead of the area:

m = [2,  2,  2,  2,  2,  2,  2,  2,  2,  2;
     2,  1,  2,  2,  1,  2,  2,  2,  2,  2;
     2,  2,  1,  2,  1,  2,  1,  2,  2,  2;
     2,  2,  1,  2,  2,  2,  1,  2,  2,  2;
     2,  2,  1,  2,  1,  2,  1,  1,  1,  1;
     2,  1,  1,  2,  1,  2,  2,  2,  2,  2;
     2,  1,  2,  2,  1,  2,  2,  2,  2,  2;
     2,  1,  2,  2,  2,  2,  2,  2,  2,  2;
     2,  2,  1,  2,  2,  2,  2,  2,  2,  2;
     2,  2,  2,  2,  2,  2,  2,  2,  2,  2 ]
threshold = 4;
cc = regionprops(logical(2-m), {'BoundingBox', 'PixelIdxList'});
bbox = vertcat(cc.BoundingBox);  %bbox(:, 3) is the width, bbox(:, 4) is the height
m(vertcat(cc(bbox(:, 4) >= threshold).PixelIdxList)) = 2
