TDOA,无线传感器网络定位算法，之TDOA(TDOA, Wireless sensor network localization algorithm, the TDOA)

自适应采样,可以根据灰度变化的不同来进行采样。matlab代码(adaptive sampling)

说明：  这是冈萨雷斯数字图像处理MATLAB版本配套的源码，里版包含了书中所用到的所有作者编写的P文件，都可以直接应用，但不可以更改。(This is Gonzalez Digital Image Processing MATLAB version supporting source, where the book contains all the authors use to prepare the P document, can be applied directly, but not be changed.)

维Logistic映射 x(n+1)=μx(n)(1-x(n)) 在3. 57 <μ < 4 的参数区域内,系统存在混沌吸引子 (Dimensional Logistic map x (n+1) = μx (n) (1-x (n)) in 3. 57 < μ < 4 parameters in the region, the systems Chaotic attractor)

十分好的，数值优化工具箱，可以用来解决L1优化问题(numerical optimization toolbox)

通过比较自编MATLAB 的k-means 算法程序和SPSS 中自带的k-means聚类工具，对两个数据集聚类，并分析了聚类结果。(By comparing the k-means algorithm program of self-compiled MATLAB with the K-means clustering tool of SPSS, two data sets are clustered and the clustering results are analyzed.)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)
