bounding rectangle of all contours of a binary image.;
#X text 655 -68 This object considers a contour to be analyzed any
group of white pixels in a black background \, for this reason you
will find useful to use pdp_bgsubstract or pdp_threshold to obtain
a correct input for pix_opencv_contours_boundingrect.;
#X text 655 -14 pix_opencv_contours_boundingrect works detecting any
white areas in the input image \, it's important to set max/min values
of the areas you want to detect to filter non interesting noise or
areas \, also sometimes you will need to use pix_opencv_morphology
to transform the contours of the shapes to be analyzed..;
