说明：  ENVI+C#二次开发环境搭建 主机操作系统：Windows10_x64 C#编辑器：Microsoft Visual Studio 2012 Ultimate ENVI5.3 SP1 win64+IDL8.5(ENVI+C#secondary development environment construction operating system:Windows10_x64 IDE:Microsoft Visual Studio 2012 Ultimate ENVI5.3 SP1 win64+IDL8.5)

说明：  短时傅里叶变换的一些简单的演示，其中有矩形窗和高斯窗(some demos for the short time fourier transform)

说明：  对图像进行处理，直接在RGB图片上画直线，矩形，多边形，写字。(Image processing, including the pictures directly on the RGB lines, rectangles, polygons, write.)

可实现答题卡阅卷系统中的图像倾斜矫正，采用Hough进行直线检测，并根据所定位的特征直线位置计算倾斜角度，再进行图像旋转，得到校正结果(chieve answer sheet scoring system image tilt correction, performed using Hough line detection, and calculates the inclination angle in accordance with the target characteristic linear position, then rotate the image, corrected results)

对应鬼成像算法，快速并且简洁，做鬼成像的朋友不要错过(Corresponding ghost imaging algorithm, fast and simple, do not miss the ghost imaging friends)

说明：  sift 图像特征提取算法源码，对研究sift算法很有帮助。(The source code of sift image feature extraction algorithm is very helpful to the research of sift algorithm.)

根据icip会议2005年度的一篇文章编写的matlab程序。包含有效果图。 运用smqt（连续均值量化变换）算法进行灰度图像增强。它比传统方法（直方图均衡化处理）的优点在于可以保证增强后图象的直方图波形不变，可以展现图象的底层结构，自动集中改进图象细节。是一种新的效果更好的灰度图象增强算法。(under icip 2005 annual meeting of an article prepared by the Matlab procedures. Includes map results. Smqt use (continuous quantitative mean transform) algorithm for gray-scale image enhancement. It is superior to the traditional method (histogram equalization processing) has the advantage can guarantee enhanced image histogram waveform unchanged. able to display images of the bottom structure, automatic focus on improving image details. Is a new and better results gray image enhancement algorithms.)

网上下的CLAHE的matlab程序，原先运行有点问题，我修改了下，保证可以通畅运行了。(CLAHE algorithm for image enhancemnt)

对视频进行基本的处理，例如载入视频，显示视频，控制播放(Basic video processing, such as loading the video, show video, control playback)

阐述压缩感知的基本原理，并通过压缩感知对图像进行复原处理(elucidate the compressed sensing theory )
