Detailed description

distanceTransform( in, dist, DIST_L2,DIST_MASK_PRECISE,CV_32F ); give good results for small square images but not for large ones above 4k by 4k. For column numbers above 4k it often gives black pixels an ED of 1.0 in stead of 0.0.

Steps to reproduce

Mat in = imread(name, IMREAD_UNCHANGED);
int numpixels = in.cols*in.rows;
    Mat dist(in.rows,in.cols,CV_32F);
    distanceTransform( in, dist, DIST_L2,DIST_MASK_PRECISE,CV_32F );
float* pf = (float*)dist.data;
   for(i=0;i<numpixels;i++) {if(in.data[i]==0 && pf[i] != 0.0)
        printf("y %4d x %4d in: %2d out: %f \n", (int) i/in.cols,i%in.rows,in.data[i],pf[i]);

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)
