HUCentralMoment.rar
- HU不变矩程序代码很多，但是没找到一个完整准确的代码。本人对其中的某些代码修正后，和matlab计算结果进行比较，结果是一致的。本程序没有利用Opencv计算Hu矩的函数，好像opencv计算的M03和M30应该对调，否则，和matlab计算不一样！对旋转、缩放的图像进行测试，HU矩也是一样的，不信可以利用提供的图片对比一下。由于HU矩比较小，程序对HU矩取对数便于查看比较。总之，程序绝对安全可靠，可直接调用。,HU moment invariants code a lot, but could

- 数字图像的边缘检测 本科毕业设计（边缘检测是数字图像处理中的重要内容。本文首先对图像的边缘检测的各种算法和算子做了总结和分析。Canny最早提出了边缘检测的三条连续准则:最优检测结果、最优定位和低重复响应,并在这些准则的基础上得到了“最优线性滤波器”―高斯函数的一阶导数。经过十几年的发展,目前已经有了对这个准则的很多改进,本文也对这个方面的工作做了小结。Demigny在理论分析和实践的基础上给出了边缘检测的离散准则,并且证明在离散准则中Canny提出的第三个准则可以被阀值操作所取代。本文利用
