摘要
在基于CCD耦合闪烁光纤阵列的快中子照相系统中,快中子图像受噪声污染较为严重。针对快中子图像中的椒盐噪声和泊松噪声,研究了形态滤波技术在降噪方面的应用。结果表明在对快中子图像处理过程中,基于二维多方向结构元素的形态滤波在滤除噪声和保持图像细节等方面效果较佳。
Fast neutron radiography system is mainly composed by a scintillation fiber array and a scientific grade optical CCD. Fast neutron images obtained by the system always suffer a serious noise disturbance. In order to weaken pepper and salt noise and Poisson noise, morphological filtration is applied to fast neutron image denoising processing. The results indicate that for fast neutron images, morphological filtration operations with two-dimensional multi-directional structure element are effective to filter the noise and hold image details.
