BKMSoftware
- 边界节点法(Boundary Knot Method)是一种被广泛使用的无网格数值方法，具有编程容易、收敛速度快等优点，被广泛关注。边界节点法的主要思想是利用控制方程的非奇异一般解的线性组合来近似方程的解，通过配点法求解出未知系数。在这整个计算过程中保持了无网格的优势。鉴于边界节点法的优点，作者开发了基于边界节点法的MATLAB工具箱用以求解一些常见的椭圆形方程控制的物理问题如Helmholtz方程控制的声学问题等，为科学研究和工程应用提供了一个简便的工具。本软件可用于科学研究和实际工程计算，

EDLinesTest
- EDLines是一种快速直线检测算子，2012年在ICCV上提出，也是目前处理直线检测最快的算法之一，该算法包含三个步骤：（1）边缘提取：利用Edge Drawing (ED)算法[28,29]从灰度图像中提取边缘片段；（2）线段检测：利用最小二乘法提取直线段；（3）线段确认：遵循Helmholtz定律，从已提取的直线段中摒弃虚假线段。EDLines算法的优越性得益于Edge Drawing (ED)算法能够从灰度图像中准确、快速、稳定地提取出光滑、完整的边缘片段。Edge Drawing (E
