A Level set based interpolation algorithm for image processing which is especially helpful for beginners.

在计算机上产生一组实验数据，首先产生一段零均值白噪声数据u（n）,令功率为 ，让u(n)通过一个三阶FIR： 得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形； (2)得出真实功率谱密度 . (3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。 (On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)

用matlab控制摄像头 对所采集的视频提取图片，再进行后续处理(Control using matlab camera captured video extract pictures, and then the subsequent processing)

岩石物理模型建模的另一种方法，同样可以翻译弹性参数与物性参数间的关系。(Another method of rock physics modeling, the same can translation parameters and physical parameters of elastic)

语音增强 提供io接口及处理的工具箱等，语音增强效果比较好(Speech enhancement provide the IO interface and the processing toolbox, and so on, the speech enhancement effect is better)

根据姚天任 现代数字信号处理 第四章，那个课后作业题编的，搞了好久，结果很理想，如果能搞成，1024点，结果会十分稳定。(music method)

系统的介绍了matlab的相关知识，并有很好的参考价值，初学者可用(System introduced matlab knowledge, and have a good reference value, can be used for beginners)

这是一个完整的EMD分解全过程，有Hilbert谱和边际谱。直接把源码复制到matlab即可。很全面。(This is a complete decomposition of the whole process of EMD, a Hilbert spectrum and marginal spectrum. Directly to the source code can be copied to the matlab. Very comprehensive.)
