根据图像灰度线性变换的算法。得到线性变换的MATLAB的程序。经仿真正确()

说明：  matlab 的非线性方程组求解多种方法得源程序(Solving nonlinear equations )

说明：  这是一个关于小波阈值图像去噪的程序，通过对分解后的系数各层进行不同的阈值处理，最后得到去噪后图像。(It s about a wavelet threshold program well worth beginners reference! )

说明：  基于小波变换的图像融合技术，不过对于不同的图片可能需要有所改动(Image fusion based on wavelet transform technique, but for different images may need to be changed)

考虑L的三个不同值：L＝256（3个数据段），L＝128(7个数据段)和L=64（15个数据段）。各自的谱估计图如上图所示。可以明显的看到，加窗明显的减小了频谱上的假谱峰，但也更加进一步平滑了谱峰。所以，对于L＝64的情况，在ω＝0.8π的谱线可以很确定的辨认，但是那两个靠近的谱峰不容易区分。对于L＝128的情况，这种情况提供了在分离和检测间最好的均衡。当然，对于在L＝256时的情况，效果是更好的，能够从谱估计图上明显的分辨出三条谱线的存在以及它们幅度关系的强弱。 除了Welch法外，还可以采用对多个周期图求平均的功率谱估计方法的其他方法如Bartlett法等等，在功率谱估计上也能取得较好的结果。(consider three different values : L = 256 (3 data), L = 128 (7 data) and L = 64 (15 data). Their spectral estimation map as shown in Fig. It is clear to see that increase significantly decreasing window of the spectrum of false peaks, but much more to further smooth the peaks. Therefore, L = 64, in the case = 0.8 spectrum can determine the identification, but that the two peaks around is not easy to distinguish. L = 128 for the situation, which provided the separation and detection among the best balanced. Of course, L = 256 in the case, the effect is better, from the spectral estimation map clearly distinguish between the three lines of the existence and their relationship to the rate of strength. In addition to Welch law, but also can be used to map multiple cycle for the average power)

说明：  MATLAB(矩阵实验室的简称)是一种专业的计算机程序，用于工程科学的矩阵数学运 算。但在以后的几年内，它逐渐发展为一种极其灵活的计算体系，用于解决各种重要的技术 问题。MATLAB 程序执行MATLAB 语言，并提供了一个极其广泛的预定义函数库，这样 就使得技术工作变得简单高效。在解决工程技术问题方面，MATLAB 比其它任何计算机语 言（包括FORTAN 和C）都简单高效。本书将介绍MATLAB 语言，并向大家展示如何运 用它去解决经典的技术问题。(MATLAB (short for Matrix Laboratory) is a professional computer program for engineering and scientific matrix math. But in later years, it gradually developed into an extremely flexible computing system for solving important technical problems. MATLAB program implementation of the MATLAB language, and provides an extremely wide range of pre-defined function library, thus making the work easy and efficient technology. In solving engineering problems, MATLAB than any other computer language (including FORTAN and C) are simple and efficient. This book introduces the MATLAB language to show you how to use it to solve the classic technical problems.)
