the image processing technique in obtaining the features present in the blood vessels of a retinal image is given

本程序描述了pca在人脸识别上的应用。并带有输入输出，可在人脸库上进行试验。(This procedure describes the pca in face recognition applications. And with the input and output can be tested on the face database.)

应用于MATLAB中对图像的非线性变换，直方图均衡化线性，平滑滤波器(Images used in MATLAB, nonlinear transformation, histogram equalization, linear smoothing filter)

该程序主要是比较对信号分别进行希尔伯特变换HT和广义希尔伯特变换GHT所得到瞬时相位的比较，结果证明GHT较HT对信号有较好抗噪特性，同时瞬时相位也可以用来重构信号，但主要起了指示的作用。(We can get instantaneous phase of the signal by HT or GHT，and the results prove that GHT has better noiseproof feature,namely robustness than HT.In the meantime,we could restruct signal using the information of instantaneous phase,but it mainly has good directives roles.)

清华张旭东老师《离散随机信号处理》教材第5章。本章首先简要复习经典谱估计的基本结论，然后分别讨论基于线性系统模型和复正弦模型的功率谱估计方法。(Qinghua Zhang Xudong teacher " discrete stochastic signal processing" textbook Chapter 5. This chapter begins with a brief review of the classical spectral estimation basic conclusion, and then discuss the power spectrum estimation based on linear system models and complex sinusoidal model approach.)

模态处理相关程序，包括时域，频率，自普，互普，相干，频响，时频分析，HHt，随机减量法等等，很不错，可以借鉴(Modal treatment-related procedures, including time domain, frequency, since the S & P, each P, coherence, frequency response, time-frequency analysis, HHt, random decrement method, etc., very good, can learn)
