- 基于小波分析和主成分分析的人脸识别研究随着社会的发展，社会各个方面对快速有效的身份验证的要求日益迫切。由 于生物特征是人的内在属性，具有很强的自身稳定性和个体差异性，因此是身份 验证的理想依据。其中利用人脸特征又是最自然直接的手段，相比其他生物特征， 它具有直接、友好、方便的特点，易于为用户接受。从而，人脸识别吸引了越来 越多来自计算机视觉和信号处理等领域的关注，成为模式识别、图像处理等学科 的研究热点。-Based on wavelet analysis and princ

- 还有就是这个函数对于有标题框的窗体支持不好，就是它裁切的只是客户区域，好在我们要制作透明窗体的场合一般用不到标题框下面就说名例程的制作过程。（我旨在说明这种透明窗体的思路及函数的用法，所以代码非常简单，并且没有必要的错误验证机制，希望大家谅解） 建立一张用于在窗体上绘制的背景图片，把要裁切的部分用一种颜色标记出来，我们叫它MaskColor，例如图片背景是绿色则MaskColor =0xFF00,也就是 RGB(0,255,0). 建立一个基于对话框的工程，修改对话框资源的属性，主要

- 将高阶时频表示引入机械故障诊断领域。介绍了Wigner 高阶矩谱(WHOS)的概念、定义。针对多分量信号Wigner 高阶矩谱的交叉项会产生“虚假信号”,结合局域波法, 提出了一种抑制WHOS交叉项的新方法。首先对复杂信号进行预处理, 利用局域波分解方法把其分解成有限个具有单分量特性的基本模式分量,然后对每个基本模式分量计算WHOS。该方法能有效抑制WHOS时频分布的交叉项。通过仿真实验和转子的故障实验,以Wigner 双谱为例, 验证了该方法的实用性,为故障诊断的特征提取提供了新的工具-Hig
