Implementation algorithm to change contrast of an image

FFT /快速傅里叶变换的基本原理，使用Visual DSP++软件实现FFT的1024位运算，并附有matlab代码。(FFT/Fast Fourier transform of the basic principles of using Visual DSP++ software FFT of 1024 operations, together with matlab code.)

非均匀傅里叶变换是传统傅里叶变换的扩展,它尤其适合于适合于非均匀采样数据或要计算 任意频率的频谱.(Nonuniform Fourier Transform (NUFT) is the extension of traditional Fourier transform,it is particularly used for nonuniform-sampled data analysis and calculating arbitrary spectral.)

该算法主要是利用randon变换实现直线，椭圆，抛物线等规则曲线的自动提取(The algorithm is the main randon transformation to realize the straight line, elliptic, parabolic curve and rules of the automatic extraction )

说明：  longge-kuta法实现，需要下载的请看看哦，绝对实用~~~~(longge-kuta method to achieve, you need to download the See Kane, absolutely practical ~ ~ ~ ~)

说明：  均值滤波对高斯噪声的影响，均值滤波是经典滤波算法，用于图像处理领域，本代码用matlab开发。(Mean Gaussian noise filter, mean filter is a classical filtering algorithm for image processing, the code developed using matlab.)

说明：  图像空域变换增强技术实践,附带matlab code(Image enhancement technology transform the practice of airspace，Matlab code attached)

通过这个实验，熟悉并能够灵活运用曲线回归或直线回归的方法去解决实际生活中的问题。(Through this experiment, familiar and flexible use of curvilinear regression or linear regression methods to solve real life problems.)

MATLAB求解灰色模型的编程，直接换掉数据就可以了 (MATLAB in gray programming model)
