opencv中的Mat类型向Eigen中的Matrix类型转换
参考:http://www.cnblogs.com/shang-slam/p/6064905.html https://forum.kde.org/viewtopic.php?f=74&t=97516 1、首先包含头文件(顺序不能错!!!先包含eigen相关库,再包含opencv库!) #inclu ......
Matrix和Mat的格式转
说明 在 opencv 中矩阵都是使用 cv::Mat 表示,但是在 slam 中使用到了 Eigen::Matrix4d 数据类型,对于它们的类型转换,可以使用 opencv 的库,代码如下: #include <opencv2/core/eigen.hpp> #include <Eigen/Co ......

简单理解 Matrix-Tree 定理
首先,我们要知道,一个矩阵的行列式可以使用高斯消元来求。 定义无向图的 Laplace 矩阵:$L_{i,j}=D_{i,j}-G_{i,j}$,其中 $D$ 是度数矩阵,满足 $i=j$ 时 $D_{i,i}=deg_i$,其余时刻 $D_{i,i}=0$;$G$ 是邻接矩阵,$G_{i,j}$ ......
