实现视频 分帧功能 按照灰度值存储 直接matlab读取(matlab vc )

本课件按逻辑编排，自始至终用实例描述；内容完整且每章相对独立；既适用于初学者，也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是一大特色。 本课件适合作为理工科高等院校研究生、本科生教学用，也可作为广大科研工程技术人员的自学。(The courseware is organized in a logical, throughout examples described complete and relatively independent of each chapter suitable for both beginners and for advanced MATLAB users. Combined with the description of MATLAB and FORTRAN, C, and other languages ​ ​ is a major feature. The courseware for science and engineering universities graduate, undergraduate teaching, can also be used as a self-study of the majority of scientific engineering and technical personnel.)

匹配追踪和正交匹配追踪，GSM中GMSK调制信号的产生，通过matlab代码。( Matching Pursuit and orthogonal matching pursuit, GSM is GMSK modulation signal generation, By matlab code.)

STFT语音信号的处理，用短时傅里叶变换进行语音信号的处理(STFT Processing a speech signal)

说明：  一篇用于样条曲面拟合的matlab程序实现的论文，对于初学者具有很好的借鉴意义。(1 for the spline fitting matlab program implementation paper for beginners with a good reference.)

根据)EF 特性中的对比度敏感度， 即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮 度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作 为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)
