lsb_matching
LSB匹配算法的实现。目前大部分都是LSB替换算法,较新的图像LSB匹配算法的嵌入和恢复我没有在其它地方找到。因此,自己写了一个,可以作为毕业设计的内容。matlab编写,经过充分测试,可用。(Image LSB Matching Algorithm,implementated using matlab )

说明: 空间信号的波达方向(Direction of Arrival,简称DOA)估计作为阵列信号处理研究的一个主要课题,在近些年来越来越得到大量的关注和研究。它可实现对空间中信源信号的准确的角度估计,实现信源方位等参数的具体精确检测,并且还具有很高的分辨力。这些特性使得DOA估计在声呐、通信及雷达等多种领域具有广阔的应用和发展前景。此程序为面阵中二维角度估计算法程序。(direction of arrival,usually called DOA,has been an important subject recently.This program contains unitary esprit)

huffmancoding
格式:[huffcodes,氢,領 ,电子] = huffmancoding(磷,氮)
%输入:p是每个字母符号的概率
(如:对= [0.3 0.2 0.2 0.2 .06 .04])
n是一个整数,决定在每个帧的符号数量
(默认:n = 1时)
%输出:huffcodes:huffmancodes
答:源熵
甲肝:平均熵编码
电子邮件:科丁效率(format : [huffcodes,H,Hav,e]=huffmancoding(p,n)
inputs: p is the probability of each alphabet symbol
( eg:p=[.3 .2 .2 .2 .06 .04] )
n is an integer that determines number of symbols at each frame
(default:n=1)
outputs: huffcodes: huffmancodes
H: source entropy
Hav: average entropy for coding
e: codding efficiency
