After I calculate the bounding boxes of each connected components , I want to extract all the vertically overlapped connected components ( completely overlapped , partially overlapped from right side and from left side) what is the best way to do it ?
this is part of my code:
fobr = imread(image);
s1 = regionprops(fobr);
X=[];
Y=[];
for i = 1:numel(s1)
X =[X; s1(i).BoundingBox(1) s1(i).BoundingBox(3)+ s1(i).BoundingBox(1)];
Y =[Y; s1(i).BoundingBox(2) s1(i).BoundingBox(4)+ s1(i).BoundingBox(2)];
end
this is X
X =
1.0e+03 *
0.0345 0.0935
