这个文件的功能是实现各种DOA估计算法的性能仿真验证，并完成DOA估计中MUSIC算法、Capon算法以及延迟相加算法性能比较的仿真验证的功能(This file is the function of various DOA estimation algorithms to achieve the performance simulation, and complete the MUSIC DOA estimation algorithm, Capon algorithm and delay sum algorithm performance comparison of the simulation function)

matlab 基于“轮廓和颜色”来识别花朵的相似性的程序。可以区别出不同类的花儿。比较有趣。(matlab based on the " contours and colors" to identify the similarity of the flowers of the procedure. Can distinguish different types of flowers. More interesting.)

it is the simulation of SVPWM technique. this technique is very popular and is useful in many simulations.

说明：  直接使用摄像头检测人脸的程序，正确率还不是很准确(Directly face the camera detection procedure, the correct rate is not very accurate)

这个程序可以修复因噪声/噪音干扰或者因抖动产生的失真的图像，Inverse滤波器, Wiener滤波器和Lucy-Richardson滤波器被使用到，同时代码还使用了光学流线分析，估计模糊的长度和角度。(This program can recover from noise/noise or distortion due to jitter generated images, Inverse filter, Wiener filter and the Lucy-Richardson filter were used, while the code also uses optical flow line analysis, estimated the length and fuzzy angle.)

Today, there is almost no area of technical endeavor that is not impacted in some way by digital image processing.We can cover only a few of these applications in the context and space of the current discussion. However, limited as it is, the material presented in this section will leave no doubt in the reader’s mind regarding the breadth and importance of digital image processing.We show in this section numerous areas of application, each of which routinely utilizes the digital image processing techniques developed in the following chapters. Many of the images shown in this section are used later in one or more of the examples given in the book. All images shown are digital.

常规地震假设地下介质是各项同性的，但实际上，是各向异性的。各向异性介质的反射系数随入射角、方位角不同而不同。(Reflection coefficient varies with incident angle and azimuthal angle.)
