基于排序差值脉冲噪声检测的彩色图像滤波方法

提出一种针对彩色图像脉冲噪声进行检测,并根据检测结果利用改进的自适应矢量中值滤波法滤除彩色图像脉冲噪声的方法。试验结果表明,该方法能够明显地减少脉冲噪声检测过程中的噪声漏判数量,有效地去除彩色图像中的脉冲噪声,滤波后不会产生新的颜色,并能较好地保持图像的边缘与细节信息。

Color image filtering algorithm based on impulse noise detection of rank-ordered pixels difference

The paper proposes an algorithm that removes the impulse noise in a color image by improved adaptive vector medi- an filtering on the basis of the impulse noise detection result.Experimental results shows that the algorithm can significantly reduce the quantity of noise pixels which do not be examined during the impulse noise detection,and can effectively remove the impulse noise of color images.Besides,the algorithm ensure the original image color and the information on the edge of the image after ill- ter...
