运用分块算法将秘密图像嵌入的一幅大图中，达到信息隐藏的效果(Block algorithm using a secret image is embedded in a large figure, to the effect of information hiding)

Retinex算法是最实用的图像处理方法以突出边界，提高对比为目的。这是最简洁的retinex实现。(Retinex provides the closest to eye perception algorithm to process the images.)

Huffman、汉明编译码:首先对给定的信源序列进行概率统计，得出信源符号的概率 p，之后进行Huffman 编码，再进行信道汉明编码。(Huffman coding and decoding: firstly given source sequence probability and statistics, the probability derived source symbols p, after Huffman coding.)

说明：  ：DBSCAN是一个基于密度的聚类算法。该算法将具有足够高密度的区域划分为簇，并可以在带有“噪声”的空间数 据库中发现任意形状的聚类。但DtLqCAN算法没有考虑非空间属性，且DBSCAN算法需扫描空间数据库中每个点的e一 邻域来寻找聚类，这使得DBSCAN算法的应用受到了一定的局限。文中提出了一种基于DBSCAN的算法，可以处理非空 间属性，同时又可以加快聚类的速度。(: DBSCAN is a density-based clustering algorithm. The algorithm has a sufficiently high density area is divided into clusters, and to be with the &quot noise&quot found in the spatial database clusters of arbitrary shape. But DtLqCAN algorithm did not consider non-spatial attributes, and spatial database DBSCAN algorithm to be scanned for each point e in the neighborhood to find a cluster, DBSCAN algorithm which makes the application subject to certain limitations. In this paper, an algorithm based on DBSCAN can handle the non-spatial attributes, can also speed up the clustering speed.)

matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )
