摘　　要：图像噪声滤除是数字图像处理领域中一项重要的方法技术。首先在对图像噪声模型及其特征介绍的基础上,对去除图像噪声的传统线性滤波和非线性滤波技术,以及针对脉冲噪声、高斯噪声等的新颖滤波理论技术进行了分析与综述,最后对图像噪声滤除的质量评价、现状与发展做了探讨与展望。Image noise filtering is an important method and technique in digital image processing. Firstly, Image noise model and its characteristics are introduced. Secondly, it is analyzed and summarized that the traditional linear filtering and nonlinear filtering, novel ftltering theory and technology for the impulsive noise and gaussian noise in image. Finally, the quality assessment, the present situation and development to image noise filtering are discussed and taken a glance into the future.
