Hi guys, I am drawing a rectangle around an object in image using following code

 {figure, imshow(BW2);
  CC = bwconncomp(BW2);
  [L Ne]=bwlabel(BW2);
  propied=regionprops(L,'BoundingBox');
  hold on
  for x=1:size(propied,1)
      rectangle('Position',propied(x).BoundingBox,'EdgeColor','g','LineWidth',2)
  end
  hold off    }

I want to know height width and strating point of the rectangle drawn. Please help me.
