Zhang Cheng-bi · Jisuanji gongcheng yu sheji · 2015
To solve the shortcomings of quantum collapsing morphological filter based on the mean-square-error quantum measurement operator when removing high density salt and pepper noise,a method for the removal of salt and pepper noise based on the quantum collapsing morphological operator was proposed.A simple noise detection operator was constructed based on the characteristic of salt and pepper noise.A new quantum measurement operator was constructed by using the mark image formed by the noise detection operator.Meanwhile,to keep the detailed information well,only the possible noise points were filtered using the quantum collapsing morphological filter.Simulation results show that the proposed method can effectively remove the high density salt and pepper noise,and has stronger ability of noise removing and shorter processing time than the other filtering methods.
