2015-05-01 05:17:41 -0600 | commented question | Matching shapes with Hausdorff and Shape Context distance I would like to highlight that I am using the Python version of OpenCV 3.0. I have just checked that in the C++ version everything seems to be working fine. Has anyone stumbled upon such a problem? |

2015-04-30 15:38:57 -0600 | asked a question | Matching shapes with Hausdorff and Shape Context distance I want to compute a distance between two shapes using the Hausdorff distance or shape context distance measure available in OpenCV 3.0. The shapes are simple white shapes on a black background. In order to find the distance between two shapes, I find contours of each shape and then pass the contours two the following functions: Could anyone please explain to me, why during the comparison the ShapeDistanceExtractor always returns 0.0, whereas the second method gives me different results depending on the position of a character on the image? |
