#X text 26 86 pix_opencv_contours_convexity :: Finds convexity defects
of the bigest contour of a binary image.;
#X text 25 228 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 pix_threshold to obtain a correct input for pix_opencv_contours_boundingrect.
;
#X text 26 281 pix_opencv_contours_boundingrect works detecting the
bigest white area in the input image \, sometimes you will need to
use pix_opencv_morphology to transform the contours of the shape to
be analyzed..;
