基于curvelet的灰度图像增强，是在变换域里通过修改系数等达到(Curvelet-based gray-scale image enhancement, in the transform domain to achieve by modifying the coefficient)

说明：  本程序是基于matlab语言编写的有关图像处理的源代码(This procedure is based on the matlab language of the source code for image processing)

说明：  多项式插值的matlab程序 多项式插值的震荡现象(Polynomial interpolation matlab program)

matlab 图像梯度化示列，对新手学习matlab很有帮助(matlab image gradient-based show out on the novice to learn matlab helpful)

dw检验Matlab源码，傻瓜型，检测值矩阵已经在程序中准备好了，无需查询。直接导入数据出结果。解压后为m文件(dw test, easyused，import the data directly to the results. detection value matrix have been ready in the program, without having to query.)

Prony的matlab工具箱，很详细，使用它可以对信号进行prony变换和分析。(Prony matlab toolbox,the signal can be prony transformation and analysis.)

提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。(presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness.)

数字信号处理，现行卷积的matlab代码，和函数文件。(Digital signal processing, the current convolution matlab code, and function files.)

此文章主要是基于matlab的通信仿真分析。(This article is based mainly on the communication matlab simulation analysis.)

由电脑随机产生一个整数，让用户去猜，如果用户猜的比电脑大，则输出“大了，再小点！”，反之则输出“小了，再大点！”(An integer randomly generated by computer, allowing users to guess, if you guess more than a computer major, then the output of the "big, and then dot!", Otherwise the output is "small, then big points!")
