摘要 提出了一种去除彩色图像噪声的快速PGF滤波算法。首先介绍了基本的PGF滤波算法,然后在分析PGF滤波算法的基础上,提出了一种简化的PGF滤波算法。最后,对该算法进行了仿真研究,仿真结果表明该算法在完成图像的噪声平滑和边缘保持的同时实现了图像的快速滤波。 A fast and efficient algorithm for noise removal in color image based on Peer Group Filter （PGF） is proposed. Firstly, the basic Peer Group Filter is introduced. And then, on the analysis of the basic Peer Group Filter, a simplified algorithm based on PGF is given to filter image. At last, the simulation is performed on the presented algorithm and the results show that the algorithm not only smoothes image and maintains edges but also reduces the computational complexity.
