MATLAB是一套用于科学计算的可视化高性能语言与软件环境。它集数值分析、矩阵运算、信号处理和图形显示于一体，构成了一个界面友好的用户环境。它的信号处理工具箱包含了各种经典的和现代的数字信号处理技术，是一个非常优秀的算法研究与辅助设计的工具。在设计数字滤波器时，通常采用MATLAB来进行辅助设计和仿真。 （2）FIR滤波器的MATLAB设计 下面以设计线性相位FIR滤波器为例介绍具体的设计方法。 线性相位FIR滤波器通常采用窗函数法设计。窗函数法设-MATLAB is a set of scientific computing for the high-performance visualization language and software environment. It combines numerical analysis, matrix computation, signal processing and integrated graphics, constituting a friendly user interface environment. The Signal Processing Toolbox includes a variety of classic and modern digital signal processing technology, is a very good algorithm research and aided design tool. The digital filter design, which are normally used MATLAB to-aided design and simulation. (2) FIR filter design MATLAB below to design linear phase FIR filter example on the specific design methods. Linear phase FIR filter normally used window function design. Window functions located

图像的组成无非是一些字符串或者一些字节组成的字符串，然而，每一个字节数据位的重要度并不是一样的，两个相邻字节往往只有低位是不一样的。例如：00100110和00100111代表了两个不同渐变度的红色，但是就人眼是分辨不出来的。最低有效位LSB算法，就是利用这一点，达到图像压缩，或者数字水印的功能。-The composition of the image is nothing more than some number of bytes or string composed of string, however, one byte for each data bit is not an important degree of the same, often only two adjacent low-byte is not the same. For example: 00100110 and 00100111 represent the gradient of two different degrees of red, but on the human eye is not out to tell. Least significant bit LSB algorithm, is to take advantage of this point, to achieve image compression, or digital watermark feature.
