图像处理，手写数字识别，GUI界面内自写数字，可以用来学习。(Image processing, digital handwriting recognition, digital write within the GUI interface, can be used to learn.)

说明：  Matlab编写的程序代码，包括基于肤色的人脸检测，根据人脸图像判别眼睛的状态（睁眼及闭眼）(Matlab program written in code, including color-based face detection, face image in accordance with the state of discriminant eyes (eyes open and eyes closed))

用matlab编写的图像恢复程序，实现压缩后图像的恢复()

MIMO2by2_16QAM_SoIC+Turbo迭代检测simulink链路,不错的(Simulink link MIMO2by2_16QAM_SoIC + Turbo iterative detection, good)

全套的DCT域数字水印源代码matlab(A full set of digital watermarking of DCT-domain source code matlab)

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.)

测距的相关内容以及采用三角测量的方法测量出来(Ranging content and the use of the triangulation method is measured)

几何库，来处理和可视化几何元素，如点，线，圆和椭圆，折线和多边形。(Geometry library to handle and visualize geometric primitives such as points, lines, circles and ellipses, polylines and polygons)

说明：  人脸检测算法对Haar特征推进，我们已经改善了大幅利用作为弱分类器的阈值中的累积概率分布点。(A face detector based on VJ algorithm (Boosting on HAAR features). We have improved the performance drastically by using mid cumulative probability distribution point as threshold for weak classifiers. )

主要有二个功能：1对图像进行SIFT特征值匹配2.显示相应的匹配效果，即核线 matlab语言的，加上C语言(There are two main functions: 1 images match SIFT eigenvalue 2. Shows the effect of the corresponding match, that is, nuclear line matlab language, together with the C language)
