学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)

卡尔曼滤波,用于加深理解卡尔曼滤波器的设计并认识扩展卡尔曼滤波器EKF和无损变化滤波器的优点(kalman filter，EKF and UKF)

This book uses MATLAB R
to analyze various applications in mathematics and me- chanics. The authors hope to encourage engineers and scientists to consider this modern programming environment as an excellent alternative to languages such as FORTRAN or C++. MATLAB1 embodies an interactive environment with a high level programming language supporting both numerical and graphical commands for two- and three-dimensional data analysis and presentation.

本文概述了使用MATLAB图像去噪的基本原理。以小波分析法为重点，对常用的几种去噪方法进行了分析比较。最后结合理论分析和实验结果，讨论了一个完整去噪算法中影响去噪性能的各种因素。(This paper outlines the basic principles of image denoising using MATLAB. Wavelet analysis, focusing on several commonly used de-noising methods were analyzed and compared. Finally, the theoretical analysis and experimental results, discusses the various factors that affect a complete de-noising algorithm denoising performance.)
