Notch
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.)

Theunmixingofhyperspectralimagery
高光谱图像的解译是遥感图像应用的一个重要环节。基于线性光谱混合模型的光谱解译技术正在越来越广泛地应用。仿真结果表明,当部分端元参与解译和分区域进行解译时,高光谱图像的解译效果会得到较显著改善。(The unmixing of Hyperspectral imagery is a critical link of the application of remote sensing imagery. Based on linear spectral mixture model, spectral unmixing technology now is being increasingly used. On the basis of it,studying unmixing ways engaged by endmembers in different conditions, comparing and discussing a more effective expression mode of endmembers.)
