Hilbert-transform

二维码扶正,对不同光照图片都有较好结果，涉及几种不同的二值化方法，采用霍夫检测直线和双线性变换扶正二维码，内含的7张图片都能扶正(Two-dimensional code righting, have a better picture of the different light result, involving several different binarization method using Hough transform to detect linear and bilinear righting two-dimensional code, embedded image 7 can be righting)

用matlab编写的进行椭圆检测的算法，用到Hough变换(Using matlab for ellipse detection algorithm, Hough transform is used)

Google Doodle推出了一款极其炫酷的LOGO，整个LOGO使用了CSS Sprite技术，利用一个初始图片和一张画满各个动作的拼接图片，实现了动画，而非传统的GIF动画图像(Google Doodle launched a very cool LOGO, LOGO using CSS Sprite entire technology, the use of an initial picture and a painting full picture stitching each action to achieve the animation, instead of the traditional animated GIF images)

说明：  基于暗通道先验的但图像去雾,暗通道先验就是基于这样一个假设：在绝大多数非天空的局部区域里，某一些像素总会有至少一个颜色通道具有很低的值。(Single Image Haze Removal Using Dark Channel Prior.)

实现两幅图像匹配。应用SSD+SAD+NCC算法的匹配，很好用的程序(Realizing Two Image Matching.Application of SSD+SAD+NCC algorithm matching, very useful program)

本论文从CT图像重建原理入手, 根据迭代重建的物理意义, 从投影模型出发, 得到投影数据, 然后利用迭代算法MART 及SIRT 重建出断层图像, 再与模型相比较, 从而确定各算法的优劣, 总结出如何选择合适的图像重建算法。(Iterative Algorithms in Computed Tomographic Reconstruction)

高精度亚像素全局运动估计的上采样梯度互相关算法(Precision subpixel global motion estimation on sampling the gradient of cross-correlation algorithm)

matlab压缩感知中的一种基于全变分正则化的重建算法——TVAL3(In compressed sensing, a reconstruction algorithm based on total variation regularization- TVAL3)

利用低通滤波器对图像进行插值放大：按放大的倍数对原图像进行插零，插零后的图片与低通滤波函数进行卷积，原先插入的零的位置自动替换为适当的插值，如此图像就已经插值放大了，图像质量还不错。(Double the number of pixels of each row and column by adding a zero value pixel between each pixel of the image.Then operate with two kinds of low-pass filters to get the enlarged image.)

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)
