[GSoC 2019] Final: Information Flow Alphamatting #2245
Conversation
Why we can't use OpenCV's flann wrapper: https://github.com/opencv/opencv/tree/master/modules/flann ? |
I found nanoflann to be the most efficient library for KDTree implementation compared to openCV's KDTree. I didnt know about flann. If flann wrapper gives comparable/better result. I can replace nanoflann with flann's function call. |

@alalek , This PR uses Eigen's Conjugate Gradient solver for sparse matrices. Is there anything in OpenCV for solving linear systems Ax=b using sparse matrices? Couldn't find any example or function for the same online in opencv docs. Please let me know. |

- Try to use relative URLs for images.
- Use markdown for embedding images.

@sunitanyk I believe there is no solver for sparse matrices in OpenCV. You can continue using Eigen implementation, but related code should be properly excluded if build configuration doesn't have Eigen ( |
