说明：  用python实现傅里叶的快速变换，实现与传统傅里叶变换不同的快速傅里叶变换，也使用了一些图形界面设计(Using Python to realize the fast Fourier transform, which is different from the traditional Fourier transform, and also using some graphic interface design)

根据高程点，绘制等高线的matlab小程序。(According elevation points, draw contour lines matlab applet.)

VS 环境下利用opencv 实现图像的傅里叶变换，输入图片，保存输出结果。(Under VS environment use opencv to achieve image Fourier transform, the input image and save the output.)

提取图像RGB颜色空间内的颜色矩。颜色矩是图像重要的颜色特征，在图像检索、比对中具有重要作用。(Calculate the color moment of each color channel in RGB color space of an image)
