好用地 matlab版本地 用hough变换进行直线提取地程序，提取最长地直线，以后会改进，可以提取累计矩阵中，局部峰值点地直线！(good land use Matlab version hough transform line extraction procedures. to extract the longest line, it will improve, can extract accumulated matrix, partial to the peak point straight!)

用Matlab写的投影法提取嘴唇 输入图像必须是规定大小的人脸(Written using Matlab projection extraction lips input image must be provided for the size of face)

多维尺度不变性的Ｃ＋＋实现，必须联合ＩＴＫ一起用，享受吧(Multi-dimensional scale invariance of the C to achieve, we must co-itk together, and enjoy it)

利用马尔科夫随机场对图像进行语义分割，通过ICm求解参数，可以运行，对初学者有较好的借鉴作用(Using Markov random field to semantic segmentation of images, through ICm solution parameters, can run, for beginners have a good reference)

Retinex理论的基础理论是物体的颜色是由物体对长波（红色）、中波（绿色）、短波（蓝色）光线的反射能力来决定的，而不是由反射光强度的绝对值来决定的，物体的色彩不受光照非均匀性的影响，具有一致性，即retinex是以色感一致性（颜色恒常性）为基础的。不同于传统的线性、非线性的只能增强图像某一类特征的方法，Retinex可以在动态范围压缩、边缘增强和颜色恒常三个方面打到平衡，因此可以对各种不同类型的图像进行自适应的增强。(The basic theory of Retinex theory is the color of the object by object for the long wavelength (red), medium (green), short wave (blue) light reflection ability to decide, rather than by the intensity of reflected light of the absolute value to decide, the color of the object under illumination nonuniformity effects, consistent with the Retinex, that is based on color constancy (color constancy based). Different from the traditional linear, nonlinear image enhancement method of only one kind of features, Retinex can be in dynamic range compression, edge enhancement and three aspects of color constancy hit the balance, thus enhancing adaptive to a variety of different types of images can be.)

将两张图像进行图像相减或相处，使两张图片叠加。(The two images are subtracted or coexisted, so that the two images are superimposed.)

本程序给出一个利用高斯法近似求解病态方程的解的例子(This program gives a Gaussian approximation method for solving equations morbid examples)

CZT变换进行信号频谱分析，解决了FFT法频域分辨不高的问题，源码开发，特别适用(Chirp Z Transform)

采用曲率的方法，等间隔三点的大小计算夹角的大小，根据阈值标记指尖指根区域。(Curvature of the methods used, such as the size of three intervals calculated the size of the angle, according to the threshold refers to the root area marked fingertips.)

自己写的分割脑组织的程序，用FCM方法分割，可以直接运行(Write their own brain tissue segmentation procedure, using FCM segmentation method can be run directly)
