说明：  我用过的一些kalman程序，希望对大家有帮助，对于初学者来说，或许有点启发。(FFT)

分别设计理想低通滤波器、巴特沃思滤波器、指数滤波器、梯形低通滤波器,并对含高斯噪声的图像进行低通滤波，截止频率自选，观察不同的截止频率,不同的滤波器的滤波效果。(Were designed for the ideal low pass filter, Butterworth filter, exponential filter, ladder low-pass filter, and Gaussian noise images with low-pass filter cutoff frequency chosen to observe the different cut-off frequency, different filter filtering device.)

分数阶fourior变换的源码，主要用来处理线性调频信号(fractional fourior transform source code, is mainly used to treat LFM)

matlab檔案，用於讀取nmea檔案，將NMEA檔案輸出成一個Class架構值(read and parsing NMEA file)

Useful library for Matlab

简单的matlab图象修正算法 采用的是sobel函数(Simple matlab edge extraction algorithm using sobel function)

能量熵的计算，包含特征值与特征向量的提取、训练样本以及最后的识别，含噪脉冲信号进行相关检测,有循环检测，周期性检测，IDW距离反比加权方法，在matlab环境中自动识别连通区域的大小。( Energy entropy calculation, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Noisy pulse correlation detection signal, There are cycle detection, periodic testing, IDW inverse distance weighting method, Automatic identification in the matlab environment the size of the connected area.)

说明：  求解语音信号的短时过零率、短时能量、短时自相关特征，分析实验结果，并能掌握借助时域分析方法所求得的参数分析语音信号的基音周期及共振峰。(The short-time zero-crossing rate, short-time energy and short-time autocorrelation characteristics of speech signal are solved, and the experimental results are analyzed. The pitch period and resonance peak of speech signal can be analyzed by the parameters obtained by time-domain analysis method.)
