高光谱 MNF

使用IDL编程来实现打开BMP，TIFF，IMG，JPEG，PNG和其他图像，实现缩放，缩放，平移，图像增强，平滑，边缘检测(Using IDL programming bmp, tiff, img, jpeg, png and other images to achieve open and zoom in, zoom, pan, image enhancement, smoothing, edge detection)

说明：  利用IDL语言来计算出影像的计算TS地表温度(use a remote sensing image calculate ts)

This Program is Simulink for the characterstics idetification of the designed Solar Cell Models

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.)

将ENVI格式转换为tiff格式的IDL源代码，放在扩展程序下使用(Converts ENVI format to tiff format of IDL source code, under the extension)

介绍了IDL的一些图像分割技术，并且附有代码例子(Some image segmentation techniques of IDL are introduced, and code examples are attached)

利用idl语言实现图像的数学形态学开闭重建运算，比提取梯度图像。(Idl language use mathematical morphological opening and closing image reconstruction operations, compared to extract gradient image.)

说明：  IDL遥感，roi的随机拆分，通过IDL控制，感兴趣区的随机选择操作(IDL Remote Sensing, Random Segmentation of ROI)

去除镶嵌过程中的空值,可以进行修复空值等。(remove nan)

   为了提升遥感应用水平，促进遥感应用产业发展，可以从认识IDL语言、了解IDL开发方式、了解IDL可视化方法开始，体会IDL语言的简便性与高效性；然后到ENVI遥感平台二次开发、IDL混合编程、ArcGIS一体化开发、企业级遥感业务化系统建设等高级应用的学习。确保学员经过培训后，能够自主学习，很好的掌握IDL语言。   现在将培训班的素材进行共享，希望更多的成员加入到IDL大家庭中。
