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。 A two-dimensional Teager filter is a non-linear edge extraction filter, which is a special case of the equalized quadratic Volterra filter. The characteristic of the two-dimensional Teager filter approximates that of the Mean-Weighted high-pass filter, that is, it has the characteristics of both local average and high-pass filter , Which can be a balanced removal of noise and enhance the image edge. Firstly, the characteristics of one-dimensional Teager filter are analyzed and the two-dimensional model of Teager filter is obtained. Finally, the two-dimensional Teager filter is used in the image processing, and satisfactory experimental results have been achieved.
