#X text 29 211 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 29 265 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..;
