| 摘 要： | 为了进一步提高开关型矢量中值滤波器滤除脉冲噪声尤其是细微噪声的能力,提出了一种基于颜色分量单独噪声检测的开关型标量和矢量混合中值滤波器(SVHMF)。与其它经典矢量滤波器相比,SVHMF最大的不同在于它是根据对像素点各个颜色单独进行噪声检测的结果,采用与之相适应的标量和矢量混和滤波方法。新滤波器可以最大限度地保护彩色图像图像像素中未被噪声干扰的颜色分量数据,从而可以进一步提高滤波效果。实验数据表明:SVHMF的滤波效果明显优于其它各类在彩色图像降噪中得到广泛应用的矢量中值滤波器。

| Abstract: | A novel vector median filter based on the component-wise noise detector,is proposed to improve the switching vector median-based filter to preserve image trivial details while effectively suppressing impulsive noises.The main difference between the proposed filter and the classical vector-based filters is that the filtered output value of each color component is calculated separately according to the results of component-wise noise detector.The proposed filter can preserve untaminated color component in the... |
