说明：  数字图像的压缩技术，特点压缩比高，压缩速度快(digital image compression technology, features a high ratio, compression speed)

设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：分别采用巴特沃斯、切比雪夫Ⅰ型、切比雪夫Ⅱ型和椭圆滤波器原型进行设 计，比较各种设计的阶数、实际阻带衰减，分析实验结果 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: respectively Butterworth, Chebyshev Ⅰ, Ⅱ and Chebyshev prototype elliptic filter design, comparing the order of the design, the actual stop-band attenuation, analysis of experimental results)

能够利用游程编码和四叉树编码完成图像二值压缩。(Can use run-length coding and quadtree coding of image binary compression.)

vrml与matlab讲解，让需要使用matlab虚拟现实工具箱的人找到自己需要的东西(vrml and matlab presentations, Virtual Reality Toolbox need to use matlab people find what they need)

matlab小波分析程序，是信号处理的基础，计算十字叉丝的在不同距离的衍射图像。( matlab wavelet analysis program, Is the basis of the signal processing, Calculation crosshairs diffraction image at different distances.)

自相关检测方法是利用信号和噪声在相关域上的差别来构造检测器的。自相关检测是将信号与自身延迟一个时延后的信号作相关处理，或用双通道接收机的输出进行相关，得到扩频信号的自相关函数(Auto-correlation detection method is the use of signal and noise in the relevant field to construct the difference detector. Autocorrelation test is a time delay signal and its delayed signal for correlation, or the output of dual-channel receiver, associated, are spread spectrum signal autocorrelation function)
