This function computes Euclidean distance transform for 3D binary image with non-trivial aspect ratio (i.e. anisotropic pixels). The algorithm uses fast optimized line-scans and is actually faster than MATLAB s BWDIST implementation of search on opti

提出一种基于搜索矩阵的自适应防碰撞算法．该算法有效利用碰撞信息，通过构造搜索矩阵，克服自适应 二又树搜索算法逐位搜索效率低的缺点．同时提出碰撞堆栈的概念，根据时隙状态，来自适应调整搜索路径，从而 减少碰撞和空闲时隙数以及传输的比特量．理论和仿真实验表明，该算法有效实用，可有效减少识别时间，提高搜 索效率-Presents a matrix of adaptive search-based anti-collision algorithm. The algorithm is the e

k-d树（k-dimensional树的简称），是一种分割k维数据空间的数据结构。主要应用于多维空间关键数据的搜索（如：范围搜索和最近邻搜索）。K-D树是二进制空间分割树的特殊的情况。-kd tree (k-dimensional tree for short), is a data structure split k-dimensional data space. Mainly used in multi-dimensional space-critical data search (eg:

是C++实现的四叉树索引可以实现2D、3D图像的插入、删除、查找，源码使用使用C++11标准实现的。值得学习。-C++ implementation of the four binary tree index can achieve 2D, 3D images of the insert, delete, search, the use of source code to achieve the use of C++11. Worth learning.
