摘　　要：二维Teager滤波器是一种非线性边缘提取滤波器,是均衡二次Volterra滤波器的一种特殊情况,其特性近似于Mean- Weighted高通滤波器,即兼有局域平均和高通滤波的特性,因而可均衡去除噪声和增强图像边缘。文中首先分析了一维Teager滤波器的特性,并得到了Teager滤波器的二维模型。最后将二维Teager滤波器应用在图像处理中,取得了满意的实验效果。Two-dimensional Teager filter is a nonlinear edge detected filter, which is a homogeneous quadratic Volterra filter. It can be approximated to a mean-weighted high-pass filter, that is, it has mean-weighted high pass filters' property. Thus, it can wipe off noise and enhance image edge. Its properties is analyzed, and a two-dimensional version of the Teager filter is derived. At last, Its application in image processing is demonstrated.
