| Abstract: | 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. |
