说明: (1)应用9×9的窗口对上述图象进行随机抽样,共抽样200块子图象;
(2)将所有子图象按列相接变成一个81维的行向量;
(3)对所有200个行向量进行KL变换,求出其对应的协方差矩阵的特征向量和特征值,按降序排列特征值以及所对应的特征向量;
(4)选择前40个最大特征值所对应的特征向量作为主元,将原图象块向这40个特征向量上投影,所获得的投影系数就是这个子块的特征向量。
(5)求出所有子块的特征向量。

PCA_tutorial
This tutorial is designed to give the reader an understanding of Principal Components
Analysis (PCA). PCA is a useful statistical technique that has found application in
fields such as face recognition and image compression, and is a common technique for
finding patterns in data of high dimension.
Before getting to a description of PCA, this tutorial first introduces mathematical
concepts that will be used in PCA. It covers standard deviation, covariance, eigenvectors
and eigenvalues. This background knowledge is meant to make the PCA section
very straightforward, but can be skipped if the concepts are already familiar.

说明: 本文提
出了基于功率预留的准入控制策略。首先介绍一种资源分配算法,该算法将可用信
道完全分配从而实现基站发射功率最小化。在此基础上,分别为小区间切换用户和
小区内切换用户设计预留策略,并根据系统的业务载荷自适应地调整功率预留量,
从而实现GOS的最优化。
(there exists a fundamental tradeoff between bandwidth and power. In this thesis, we
propose a novel admission control scheme based on power reservation. Foremost, we
introduce a joint subchannel and power allocation algorithm for WiMAX system, which
minimizes the overall downlink transmit power by utilizing all available subchannels.
Based on this, we propose two power reservation schemes for inter-cell handoff calls and
intra-cell handoff calls, respectively. The amount of reserved power is determined in an
adaptive manner for optimizing the metric of Grade of Service(GoS).
