hy all,
using findContours on this image (or any other binarised image...)
i have strange result :
has you can see, somme point are negative, so when i want to draw coutours, it's crash.
here is extract of my code :
img_inrange.copyTo(img_contour); Canny( img_contour, img_contour, 100, 200, 3 ); findContours(img_contour, contours, CV_RETR_LIST , CV_CHAIN_APPROX_NONE);
who can help mee ?
