摘要
本文结合线性滤波器和非线性滤波器的优点,提出了一种基于线性、非线性的混合滤波算法。该算法比均值滤波器和中值滤波器具有更好的抑制噪声的能力,能较好地保持图像的边缘,反映图像的几何结构和细节特性。在此基础上又提出了改进算法及其快速实现,进一步改善了滤波性能。该滤波器计算量适中,具有较好的实时性。
A hybrid filter which combines linear and nonlinear filters is proposed for still images. It performs better than average filters and median filters on noise reduction while retaining edges of an image. We also suggest a modified version and fast implementation of this filter to further improve its performance. Because of its reduced computation complexity, this filter excels in real-time tasks.
