Possible bug in distanceTransform if you use CV_DIST_MASK_PRECISE
Hi,
currently I'm wirting on my OpenCV code here and I noticed some weird behaviour in my data processing. I looked into it and it seems that if you use
cv::distanceTransform(copy, copy, CV_DIST_L2, CV_DIST_MASK_PRECISE);
which results in [Felzenszwalb04] instead of [Borgefors86] there are wrong values introduced in the Mat after a given size (it starts at 4098 I think). The pattern looks quite regular so it's likely some memory access problem.
I provide some sample code at http://pastebin.com/UNwMF8uU demonstrating the issue.
