基于数学形态学的CCD降噪技术

The CCD de-noising technology based on mathematical morphology

在阐述数学形态学的原理、分析CCD的主要噪声特点及传统去噪方法的基础上,设计了形态学交替混合滤波器(包括滤波算法设计及结构元素选择).Matlab仿真结果表明,该方法可以较好地抑制CCD信号中的散粒噪声、复位噪声及高频噪声.

This paper expatiates on the theory of mathematical morphology and analyzes the characteristics of CCD noise and the traditional de-noise methods.A hological alternating hybrid filter is designed,including the filter arithmetic design and the structural element selection.Matlab simulation results show that this method can restrain the CCD signal shot noise,reset noise and high frequency noise.
