2015-04-13 16:28:37 -0600 | asked a question | Position of a Roi in a mat Is it possible to know the position of a ROI made from a Mat if you pass both of them as argument of a function ? |

2015-04-07 17:54:05 -0600 | asked a question | Cmake can't find OpenCV I was using OpenCv from the repo under Fedora 21. Since I wanted to use the latest version, I downloaded the git version and followed the install instruction here. However when I try to compile my old project which worked fine with the repo it doesn't seem to work anymore : Here is my CMakeList.txt : Appears I need to change all my include with "cv.h" to "opencv/cv.h". But it means my program will not work with someone who installed it from the repo. Why is that ? [EDIT] even better if someone knows how I can make CMake use a version that I would install locally =) ! |
2015-04-07 15:25:03 -0600 | asked a question | Voronoi lines I'm trying to have an image with the voronoi line (the point on the image which are at an equal distance of at least to 0-value pixel). I know of Using delaunay here isn't really an option because I have only an image with lines and no points to give to Is there any "easy way" to get all those point at equal distance of 0-value pixel ? If I could not have to reimplement a Voronoi less efficient than the one implemented I'll be really glad. Here is a (bad) image made under GIMP. If the red lines are the 0-values point, then the black line would be my Voronoi lines : Sorry for the very badly drawn drawing ! What I tried for now :
For exemple, here are my results with Laplace and Sobel using the label. The Laplace one here is perfect because non of the lines are connected. If I were to put a "dead-end" (connect the two line on top for example), my top line would disappear. And I don't want that :) Thanks ! |

2015-04-07 04:49:11 -0600 | commented question | Using Sobel on label's of DistanceTransform Thanks it solved my problem. But maybe you meant CV_32F ;) |
2015-04-06 22:46:26 -0600 | asked a question | Using Sobel on label's of DistanceTransform I'm trying to use Sobel on the Distance Transform label as a way to only have Voronoi lines in the resulting map. This is my code so far : But when I try to run this little program I hit this error : I don't really understand what it means and how I got this error... Any help is appreciated. |
