Otsu-最大类间方差Matlab代码 最大类间方差法原理：最大类间方差法是由日本学者大津于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2 部分。背景和目标之间的类间方差 ％ 大,说明构成图像的2 部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2 部 ％ 分差别变小。(Otsu- Otsu Matlab code Otsu Principle : Otsu law by Japanese scholars in the large-1979's, is an adaptive threshold established methodology, also known as big-law, referred to Otsu. It is based on image characteristics of the gray image can be divided into the background and objectives of Part 2. Background and objectives between the between-class variance%, which meant that the two images form part of the greater difference, When some background into the wrong target or part of the background into the wrong target will lead to sub-2% difference becomes smaller.)

利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)

实现多输入单输出的预测功能，预测精度高，程序操作简单，易于修改应用。(The prediction function of multi input and single output is realized. The prediction accuracy is high, the program operation is simple, and it is easy to modify the application.)

shangjiao6.m为主程序；pcode.m为产生伪码的子程序；bu.m为进行补0的子程序（为了使得进行FFT和IFFT的点数满足2的N次方个） c_b.m为数据进行串并转换的子程序。(shangjiao6.m-based procedures pcode.m for producing pseudo-code subroutine bu.m for fill 0 Subroutine (carried out in order to make the point FFT and IFFT of the N-th power to meet the 2 months) c_b.m for data for string and conversion subroutine.)
