工具箱，控制理论发展的最新成果，很好的东西，分分享(Toolbox, the latest development of control theory, very good, sub-share)

对阈值隐藏图像的提取。已经经过阈值隐藏算法隐藏的二值图像，通过此算法进行信息提取。(Hidden images on the extraction threshold. Hiding algorithm has been hidden threshold binary image information extracted by this algorithm.)

对于数字图像处理技术中，图像的编码分为RGB和HIS，这个资料讲述了在matlab中如何将两种编码转换，在实际应用中非常广泛！(For digital image processing technology, image coding is divided into RGB and HIS, this information describes how the two kinds in the matlab code conversion, in a wide range of practical applications!)

工具箱说明文件，帮助初学者快速掌握工具箱用法 很好用，不过是英文的啊(svm lib Toolbox documentation to help beginners to quickly master the use of the toolbox Useful, but ah English)

QR码作为一种可高速、全方位识别的二维条码,已经在各行各业中得到了应用,并具有很大发展潜力.本文针对QR码图像的识别过程中可能遇到的图像噪声干扰、QR码占实际拍摄图像的一部分、倾斜、几何失真等问题进行了研究,提出了通过改进型中值滤波去除噪声,使用QR码符号特性定位并对倾斜图像进行旋转,对失真不严重的图像采用控制点变换和双线性插值方法进行几何校正.实验证明, 本文的方法简单有效, 可以用于提高条码的正确识别率.(As a high-speed, full identification of the two-dimensional bar code, QR code has been applied in all walks of life, and also has great potential for development. In this paper, aiming at QR code image recognition process may be encountered in noise interference, QR code accounting for the actual captured image just a part, slant, geometric distortion, and other issues have been studied, put forward through improved median filter to remove noise, use QR code symbol characteristics to locate and rotate the tilted image, distortion which is not serious use control-point transform and spatial bilinear interpolation method for geometric correction. The results show that this method is simple and effective, can be used to improve the QR code correct recognition rate.)

对于持续时间为500s的两个LFM信号，其初始频率分别为0.1Hz、0.3Hz，中止频率分别为0.3Hz、0.1Hz，在不含噪声和含有噪声（ ）的情况下，仿真(for the duration of the two 500s LFM, the initial frequency of 0.1Hz. 0.3Hz, suspension frequencies of 0.3Hz, 0.1Hz. In noise-free and noisy () cases, the simulation)
