三分之一倍频程表示的短时傅里叶变换，需要时域分析工具箱(One-third octave express the short-time Fourier transform, the need for time-domain analysis toolbox)

It is a call ender application

Angle between two points

提出了一种新的基于小波包变换 和偏斜度的检测方法。该方法利用小波包对图像进行多尺度分解，解决了高频段分辨率低的问题； 并提出了一个基于偏斜度的高斯判别准则，用于对小波包分解系数进行高斯性检验，最终得到了 小目标的精确检测(The wavelet packets were applied to decompose the image into pyramid subbands at different scales and solve the problem of the higher frequencies having lower resolutions. Then a Gaussian measurement criterion based on skewness was proposed to test the Gaussian nature of the wavelet packet coefficients and finally the exact detection result was obtained. )

matlab应用接口编程设计基础，术语应用的扩展(matlab application interface programming design based on the term application extension)

fz作业，老师叫我们回家做的滥作业，相信大家不会想下载(fz operations, the teacher told us to go home so indiscriminate operations, I believe we would not want to download)

包括对于高斯混合模型GMM的三个PDF文档，有GMM的发展历史，学习笔记，以及相关中文文献(Including the three PDF documents Gauss mixture model of GMM, development history, the GMM study notes, and related Chinese literature)

说明：  《MATLAB6.x信号处理》pdf文档，希望对大家有用哈(err)

说明：  傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。(ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier transform to denoising the speech signal.)
