hough变换，matlab编程。Hough变换是一种使用表决原理的参数估计技术。其原理是利用图像空间和Hough参数空间的点－线对偶性，把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计，然后在Hough参数空间寻找累加器峰值的方法检测直线。(hough transform, matlab programming. Hough transform is a vote on the principle of using a parameter estimation techniques. The principle is the point of the image space using the Hough parameter space and line- duality converting the detection problem in the image space to the parameter space. By a simple statistical accumulated in the parameter space, and then in the Hough parameter space to find a method of detecting the peak accumulator line.)

这是一本关于地球物理反演方法的经典著作《Parameter Estimation and Inverse Problems》，学地球物理的可以看看。(this book is for geophysics inverse problem base study. worth reading if you are a student of geophysics.)

本文提出了一种基于独立分量分析的音频数字水印方法。嵌入水印时,对原始音频文件进行一级小波分解,在分解 得到的逼近分量中利用随机混合方法嵌入水印后进行小波逆变换形成嵌入水印的音频文件。仿真实验结果表明这种方 法的强鲁棒性和可行性。(Abstract:Audio p roduction is one of the important digital multimedias, which transmit becomes more and more convenient. To p revent the multimedia content from being stolen or illegally used, audio content p rotection techniques become increasingly impor2 tant so that the potential of these app lications can be reached. As the importantmethod of copyright p rotection, the digitalwater2 marking technology has been acquired widely recognition and research. This paper p resents a method of digital audio watermark2 ing based on independent component analysis. When embedding watermarking, the original audio is decomposed by single2level discrete 12D wavelet transform, watermarking is embedded by mixing randomly to the app roximation coefficient vector obtained, and the audio is single2level reconstructed receiving audio havingwatermarking. Emulated experiment results show that thismeth2 od is robust and feasible.)

说明：  为了降低卫星链路在恶劣天气下对信号严重的衰减，选择一种好的信道编码对保证信号的质量具有重要的意义(THE SATELLITE COMUNICATION SYSTEM LINK DESIGN BASED ON VSAT)

将软件的建模功能用专业的软件实现，这个很不错，可以完全实现自动处理(The software' s modeling capabilities with professional software, this is very good, you can completely automate processing)

二维数据成像利器，看波场快照、地震记录专用(Two-dimensional data imaging tool, see the wave field snapshots, seismogram special)

（1）掌握动态联编的概念； （2）掌握虚函数和纯虚函数的使用方法； （3）掌握抽象类的使用。 (this is a good passage for college student)
