I have a Mat like this:
int sizes[] = { 5, 5, 5 };
Mat a(3, sizes, CV_8UC1, cv::Scalar(0));
I want to get a sub-matrix in some specified plane (X-Y, X-Z, or Y-Z) and apply a distance transform to that matrix. I tried something like:
Range ranges[] = {Range(0, 1), Range::all(), Range::all()};
Mat b(a, ranges);
But when I perform:
distanceTransform(b, c, CV_DIST_L2, CV_DIST_MASK_PRECISE);
I got this error:
OpenCV Error: Bad flag (parameter or structure field) (Unrecognized or unsupported array type)
I gess that's because the program doesn't slice the 3d matrix properly.
I also looked at NAryMatIterator but it doesnt seem to be what I need.
Thanks!
