  • resize_img
    在使用envi中的band_math时需要将两张图像设置为相同的行和列,改程序解决了该问题(In use of envi band_math need two images set to the same rows and columns, change the program to solve the problem)

  • ENVI_HANTS_Tool
    NDVI时间序列谐波分析法(Harmonic Analysis of NDVI Time-Series)(简称Hants )对时间序列数据进行平滑。该方法是一种新的物候分析方法,可用于定量化的监测植被动态变化。其核心算法是傅里叶变换和最小二乘法拟合, 即把时间波谱数据分解成许多不同频率的正弦曲线和余弦曲线,从中选取若干个能够反映时间序列特征的曲线进行叠加,以达到时间序列数据的重建目的。(The NDVI Time Series Harmonic Analysis of NDVI Time Series (Hants) smoothes Time Series data. This method is a new phenological analysis method, which can be used for quantitative monitoring of dynamic changes of vegetation. The core algorithm is the Fourier transform and least squares fitting, namely the time spectrum data is decomposed into many different frequency sine curve and cosine curve, selected from several can reflect the characteristics of time sequence curve superposition, the reconstruction of the time series data in order to achieve purpose.)

  • SVM
    高光谱图像的分类,适合各种光谱数据或者RGB图像。只需要调整输出路径就好了。(Hyperspectral image classification, for a variety of spectral data or RGB images. Only you need to adjust the output path just fine.)
