B样条曲线控制点反求 生成曲线 求插补点(b-spline interpolation)

比较强的图像边缘检测算法，可用于图像分割，重建等，可以运行，可用于交流学习或者研究，最新出来的算法，是一篇文章上的算法程序，本人检验过可行，价值很大，希望能与大家分享，共同进步，谢谢大家

用于运动捕获数据的降维，可以提取极值点，进行关键帧提取或运动分割(Dimensionality reduction for motion capture data can be extracted extreme points, keyframe extraction or motion segmentation)

OFDM下行的仿真1、产生要传输随机数； 2、进行调制； 3、串并转换； 4、进行IFFT操作（代码中有用到共轭对称向量的IFFT为实数进行简化计算）； 5、增加循环前缀； 6、并串转换； 7、输出前滤波； 8、增加信道噪声（加性高斯白噪声）； 9、接收端串并转换； 10、去除循环前缀； 11、进行FFT变换； 12、信号解调； 13、误比特率计算； (OFDM downlink simulation 1, have to be transmitted random number 2, the modulation 3 series and transforms 4, the IFFT operation (code useful to conjugate symmetric vector of the IFFT of real numbers to simplify calculations) 5, the increase in circulating prefix 6, and string conversion 7, the output before the filter 8, increased channel noise (additive white Gaussian noise) 9, the receiver string and conversion 10, removal of cyclic prefix 11, the FFT transform 12 , the signal demodulation 13, bit error rate )

for perceptron training, there is no test program

matlab 入门书籍，包括矩阵运算，微分方程，非线性方程求解，画图功能(matlab books for , including matrix operations, differential equations, nonlinear equations, and drawing functions)

结合粒子群优化算法和和声搜索算法的优点，有效将群智能思想和随机全局搜索相融合，在几个函数优化问题中得到了验证 (Combining particle swarm optimization algorithm and harmony search algorithm advantage, effective will swarm intelligence thought and random global search phase fusion, in several function optimization problem has been proved )

SA, Simulated Annealing, Traveling Salesman Problem,

实现信号处理中QAM调制、过信道、解调部分。其中QAM调制部分可改符号点数，M阶数，信道加高斯白噪声、时延、多径，调制解调均有星座图。通过本代码，可学习QAM调制解调，或者通信系统的知识。(To achieve QAM modulation, signal processing over channel, a demodulation section. QAM modulation section can be changed symbolic points M order channel additive white Gaussian noise, delay, multipath, the modem has constellation diagram. QAM modulation and demodulation, or communication system knowledge through this code, you can learn.)

说明：  水声目标识别34页图2-17仿真 分别使用仿真信号和实际船舶辐射噪声信号进行解调处理获得解调谱，以比较上述三种方法的解调效果。(The simulation signal and the actual ship radiated noise signal are respectively used to demodulate and obtain the demodulation spectrum to compare the demodulation effect of the above three methods.)
