数字水印的实现工具optimark

图像的预处理 运用了使图像变得平滑的一般处理 即对高斯函数的卷积操作 高斯函数在图像处理中用作预平滑核 这样可以将图片背景模糊化 同时锐化图像

用c编写得图像镜像得源代码，希望对大家有用 -C was used to prepare a mirror image source code, useful for all of us hope

本dll文件实现了点，线段，直线，多边形的类，完成了多边形的一些常用方法：求面积，判断是否是简单多边形，求多边形并，判断两个多边形的位置关系等方法。-the dll file to achieve a point, line, line, polygon category, completed the polygons of some commonly used methods : for the area to determine whether it is simple polygon, and polygons seek to determine the location of two polygons relations methods.

计算机图形学中用经典算法实现的绘图程序，包括直线生成、圆弧生成、线段裁剪、多边形裁剪等-Computer graphics with the classic algorithm of mapping procedures, including a straight-line generation, arc formation, line cutting, cutting, such as polygon

三维骨架运动数据bvh的读取，显示,基于B样条的路径编辑，运动编辑，多种骨架插值算法（四元数+B样条插值）-3D skeleton movement data bvh read, display, based on B-spline path of the editors, sports editors, Skeleton various interpolation algorithm (Quaternion B-spline interpolation)

在dos下模拟时钟运转的c语言源码-in simulated clock operation of the source language c

This library implements the KLT Tracking algorithm [2004] for Feature Tracking in Video useful in computer vision tasks like object recognition, image indexing, tracking and structure from motion. This implementation uses programmable Graphics Hardware to achieve considerable speedup in the running time of the GPU-based implementation.

vB做动画写的一个工具，动画里经常要考虑透明图像，这个工具实现了把图片变成透明的算法，希望对大家有用:)-studyalso shows VB animation was done by a tool, animation frequently to consider transparent images, This tool achieved the picture becomes transparent algorithm, we hope to useful :)

是在C编程环境下的玫瑰图形源程序。-is in the C programming environment Rose graphics source.

本代码实现了SIFT算法，首先获得差分图像尺度空间，寻找局部极值点，找到关键点，然后，对关键点生成特征描述符。实验效果很好。
