Fisher线性鉴别分析已成为特征抽取的最为有效的方法之一 .但是在高维、小样本情况下如何抽取Fisher最优鉴别特征仍是一个困难的、至今没有彻底解决的问题 .文中引入压缩映射和同构映射的思想 ,从理论上巧妙地解决了高维、奇异情况下最优鉴别矢量集的求解问题 ,而且该方法求解最优鉴别矢量集的全过程只需要在一个低维的变换空间内进行 ,这与传统方法相比极大地降低了计算量 .在此理论基础上 ,进一步为高维、小样本情况下的最优鉴别分析方法建立了一个通用的算法框架 ,即先作K L变换 ,再用Fisher鉴别变换作二次特征抽取 .基于该算法框架 ,提出了组合线性鉴别法 ,该方法综合利用了F S鉴别和J Y鉴别的优点 ,同时消除了二者的弱点 .在ORL标准人脸库上的试验表明 ,组合鉴别法所抽取的特征在普通的最小距离分类器和最近邻分类器下均达到 97 的正确识别率 ,而且识别结果十分稳定 .该结果大大优于经典的特征脸和Fisherfaces方法的识别结果
Fisher linear discrimination analysis has become one of the most effective way to feature extraction, but in the case of high dimension and small sample how to extract Fisher optimal identification features is still a difficult, still hasn t completely solve the problem. In this paper, introducing the idea of compression mapping and isomorphism, ingeniously solved the high-dimensional theoretically, singular case to solve the problem of optimal identification vector set, and the whole process of the method to solve the optimal identification of vector set just in a low dimensional transformation space, compared with the traditional method greatly reduces the amount of calculation. Based on this theory, further to high dimension and small sample situation of optimal discrimination analysis method to establish the framework, a generic algorithm is first as K L transform, reoccupy Fisher identification transformations as a secondary feature extraction.

均值滤波、中值滤波、维纳滤波和基于小波变换的软阈值法和硬阈值法是常用的几种图像去噪方
法，通过对添加了不同噪声的图像进行了仿真实验。实验结果进一步验证了均值滤波在去除噪声的同时造成了
图像边缘一定程度的模糊，中值滤波能相对较好的保留了图像的边缘，维纳滤波对高斯白噪声去噪效果较好但
计算量大，相比较小波阈值法去噪是目前较好的的去噪方法，通过选取合适的阈值可以得到较为理想的去噪效
果。
Average filter，median filter，Wiener filter，and sofl and hard threshold method based on wavelet
transform are most commonly of several denoising methods ． A simulated experiment was carried by adding different
noise images． The experimental results demonstrate that the average filter can remove noise but it cause the
image edge blurred in a certain degree， the median filter can give a relatively fine retained image edge，and the
Wiener filter require much of calculation． Comparatively the threshold denoising in wavelet domain is a better denoising
method at present． It can be obtained an ideal effect in denoising by choosing appropriate threshold values． (2012-12-19, C/C++, 642KB, 下载62次)
