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

在信号处理中，它通常是可取的是能够执行某种降噪图像或信号。中值滤波是一种非线性数字滤波技术，通常用于去除噪声。这种噪声是一个典型的前处理步骤，提高后处理的结果（例如，边缘检测在图像）。中值滤波是非常广泛的应用在数字图像处理中，在一定的条件下，它保留了边缘，去除噪声-In signal processing, it is often desirable to be able to perform some kind of noise reduction on an image or signal.
