一种二值水印嵌入的方法

基于灭点理论的摄像机标定程序，首先选取具有平行性质的两对线，标好坐标(Based on Vanishing Point camera calibration procedures, first select the character with two pairs of parallel lines, marking a good coordinate)

图像去噪，是目前图像处理领域对高斯白噪声效果最好的去噪算法(image denoising)

计算图像的二维图像熵,在一维熵的基础上引入能够反映灰度分布空间特征的特征量组成图像的二维熵 包括 计算图像二维图像熵的函数文件 H_img2d.m 调用该函数的代码 H_img2d_test.m 以及测试代码用图像文件 boy.jpg(computing two dimensional image entropy of an image)

进行边界轮廓标定的snake算法工具箱，距离势能 gvf 以及传统sanke等各种snake(The boundary contour of the snake algorithm calibration kit, from the potential gvf and other traditional snake sanke)

这是一个非常好的图象分割程序,基于纹理分割的,保证别人没有上传过(very good image segtation)

采用matlab编制，可用于画随时间、地点变化的海流矢量图(The source code is written with matlab and can be used to draw time and space varying ocean currents)

shape from shaping 3D重构(shape from shaping 3D reconstructed)

清华大学本科生课程设计，实现平面点集的三角剖分！用外接圆测试剖分的正确性。算法执行速度较快，但存在狭长三角形！(Tsinghua University undergraduate courses designed to achieve the triangulation of the set of points in the plane! Circumcircle test the correctness of the split. Algorithms perform faster, but there is a long, narrow triangle!)

说明：  基于SIFT的图像配准程序 SIFT特征匹配算法是目前国内外特征点匹配研究领域的热点与难点,其匹配能力较强,可以处理两幅图像之间发生平移、旋转、仿射变换情况下的匹配问题,甚至在某种程度上对任意角度拍摄的图像也具备较为稳定的特征匹配能力(SIFT-based image registration procedure is the SIFT feature matching algorithm for matching feature points at home and abroad a hot area of research and the difficulties in matching their ability to deal with translation between two images, rotation, affine transformation to match the case of problems, and even to some extent in any angle images will also be able to match the characteristics of a more stable capacity)

展开相位是物体表面三维形貌测量中一项关键技术，为了避免相位展开过程中的误差传播效应，Saldner和Huntlye等提出了时间相位展开方法。用matlab模拟了时间相位展开的方法(Expand the phase surface 3D topography measurement of a key technology in order to avoid the phase unwrapping process of error propagation effects, Saldner and Huntlye temporal phase unwrapping. Using matlab to simulate the temporal phase unwrapping method)
