【摘要】 提出了一种改进的快速矢量中值滤波器(IFIVF,improved fast impulsive vector filter)。IFIVF以FIVF为基础,通过peer group和边缘检测技术构建新的噪声检测器。与其它矢量中值滤波器(VMF)相比,新的噪声检测方法使得IFIVF不但可以对彩色图像中的随机和固定脉冲噪声进行有效压制,还可以进一步提高FIVF的滤波视觉效果。更多还原

【Abstract】 An improved fast impulsive vector flter(IFIVF)for the impulsive noise removal in color images if presented.The proposed filter employs the switching scheme based on the noise detection mechanism using the so-called peer group concept and edge detection method.Compared with other commonly used vector median filters,the proposed filter consistently yields very good results in suppressing both the random and fixed-valued impulsive noise.The main advantage of the proposed filter is its enormous computational speed,which enables efficient filtering of color images in real-time applications.更多还原
