this is the program to calculate the symmetrical fault in the three phase power system

this programme implements David Lowe s Scale Invariant Feature Transform (SIFT) algorithm to a grayscale image

calculate joint entropy of two images

说明：  利用小波变换中的多尺度变换进行图像边缘特征检测的主程序！(Using multi-scale wavelet transform in image edge detection of the main program features!)

哈弗曼编码的原程序代码，用于嵌入图像编码的源程序。(Havermann encoding the original program code, source code for the embedded image.)

Viterbi 编解码算法仿真实现，回环调试成功！(Viterbi coder and decoder matlab code)

基于离散余弦变换的最小二乘法相位解包裹(DCT),peaks生成包裹相位图，用LS-DCT解包裹得到去包裹的真实相位图(Based on Discrete Cosine Transform method of least squares phase unwrapping (DCT), peaks generated wrapped phase diagram obtained by LS-DCT unwrapping unwrapping the true phase diagram)

小波的应用，需要用到小波基。例如在信号处理的各种应用中。用小波基才能生成小波函数。(Wavelet applications require the use of wavelet bases. Such as in various applications of signal processing. Wavelets can be used to generate wavelet functions.)

Pf粒子滤波实现的目标跟踪程序，可实现针对非高斯噪声情况下的跟踪(Pf particle filter to achieve tracking procedures, can be non-Gaussian noise for tracking cases)
