这是我做的一个二维傅里叶变换的程序，可以对图像进行2DFFT变换得到频谱图，并利用2DIFFT得到原图像(I do a two-dimensional Fourier transform procedure, 2DFFT transform spectrogram image and utilize 2DIFFT original image)

说明：  在VC中实现了使用Moravec算子对遥感影像进行特征点的提取，缺点是速度较慢。不过提取效果不错！(Implemented in VC using Moravec operator of remote sensing images feature point extraction, the disadvantage is slow. However, extracting good results!)

利用matlab进行插值法亚像素边缘检测，提取零件轮廓(Subpixel edge contour extraction)

用于火焰尖角、圆形度、纹理的测量以及图像颜色、矩阵、边缘直方图的测量(For flame sharp corners, roundness, texture measurements, and image color, matrix, edge histogram measurements)

说明：  将girl 图像进行分割，达到2*4的图像分割结果。并使用tight_subplot函数将分割间距变小。(The girl image is segmented to achieve a 2*4 image segmentation result. And use the tight_subplot function to make the division interval smaller.)

MATLAB编写的增强图像分辨率的程序，可以提高图像分辨率，使图像更加清晰。(Written MATLAB program enhanced image resolution, image resolution can be improved to make the image clearer.)

这是关于将jpeg压缩的具体算法的原始论文，利于学习。pdf格式(a pdf file about how to encode jpeg,this is the original paper good for your learning)

光伏逆变系统中的最大功率点跟踪算法，采用的是变步长的扰动观察法，可以快速收敛(mppt method using variable step size perturb and observe method, it can converge faster.)

用对偶分裂算法处理乘性噪声如盐椒噪声（L1+TV），参数由电脑自动选取，matlab程序(A Duality-Based Splitting Method for L1-TV Image Restoration with Automatic Regularization Parameter Choice)

说明：  四种算子(sobel,prewitt,roberts,marr)进行图像边缘检测的matlab源码.(Operators of four (sobel, prewitt, roberts, marr) image edge detection matlab source.)
