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.

The appropriate reference information is <http://www.mathworks.com/help/techdoc/ref/rectangle_props.html here>
rects = findobj(gca,'type','rectangle');
for K = 1:length(rects)
rpos = get(rects(K),'Position');
fprintf(1, 'Rectangle #%d: height %g, width %g at (%g,%g)\n', ...
rpos(3), rpos(4), rpos(1), rpos(2));
end
