Em_extraction

该代码用于对错误匹配点进行过滤操作，即去除错误的匹配点(The code is used to remove the wrong match points,and make sure the right matching.)

用均值滤波、中值滤波、维纳滤波法给加高斯噪声的图像去噪(Using the mean filter, median filter, Wiener filter to add the Gaussian noise image denoising)

陷波器是一种特殊的带阻滤波器,其阻带在理想情况下只有一个频率点,因此也被称为点阻滤波器。这种滤波器主要用于消除某个特定频率的干扰,例如,在各种测量仪器和数据采集系统中用于消除电源干扰的工频陷波器。该程序实现利用陷波滤波器消除图像的电源干扰。(Notch is a special band rejection filter, the stop band in the ideal case , only one frequency , it is also known as point-stop filter . This filter is mainly used to eliminate the interference of a particular frequency , for example , in a variety of measuring instruments and data acquisition system is used to eliminate the power line frequency interference notch filter . The program implements the use of a notch filter to eliminate power disturbances image.)

基于Matlab软件编程实现MC算法对人体脑部MRI图像进行面绘制三维重建；利用三维旋转变换和动画函数对脑部图形进行动画显示(Based on Matlab software programming realize MC algorithm on human brain MRI images drawn face 3 d reconstruction Use of 3 d rotation transformation and animation of brain function graph animation display)

说明：  边缘检测技术用于医学图像的边缘检测， 对特定目标分割前做边缘定位(objective edge detectiong for medical AI platform.)

Probabilistic Latent Semantic Analysis模型实现，用于目标识别或文本识别(Probabilistic Latent Semantic Analysis model for target recognition or text recognition)

数字图像处理，K-SVD字典学习方法，信号的稀疏与冗余表示理论，图像压缩，图像去噪(Digital image processing, K-SVD dictionary learning methods, sparse and redundant signal representation theory, image compression, image denoising)

一种应用于图像处理领域的简单变换方法,简化哈尔小波变换的新算法 (A kind of image processing applied to a simple transform, Haar wavelet transform of a new simplified algorithm)
