本文提出一种除噪滤波与边缘检测同时进行的方法——非线性检测滤波器法.该方法基于中值滤波器和非线性Laplace算子数学方法.理论与实验表明:该非线性滤波器很少损失边缘信息,而且速度快.
In this paper, we present a new method of non-linearity detection based on median filter and non-linear Laplace operator.A theoretical and experimental results show that the nonlinear filter Less loss of edge information, and faster.
