摘要
本文基于统计信息———局部均值和局部方差 ,探讨了数字图像对比度增强和噪声滤波方法。尤其对加性噪声和乘性噪声 ,设计了相应的滤波器。仿真结果表明 ,本文的方法实现简单、运算速度较快 。
Based on statistical information of local mean and local variance,image contrast enhancement and noise filtering is discussed.Corresponding filter is designed especially for additive and multiplicative noise.Experimental results show that the method presented in this paper has the characteristic of simple realization and rapid operation,a new approach is supplied for real-time image processing.
