数字图像的平滑处理方法研究

Study on Smooth Processing Methods of Digital Image

图像在获取和传输过程中,会受到各种噪声的干扰,使图像退化,质量下降,对分析图像不利。图像的平滑或去噪一直是数字图像处理技术中的一项重要工作。为此,论述了在空间域中的各种数字图像平滑技术方法。

Any picture would be effected by all kinds of noise during the course of acquisition and transition which would lead to the degradation of a picture. The image and the character of a picture indistinct which is an disadvantage for image analyses. Image smoothing is a vel image processing technology. The paper mainly discusses the various image smoothing methods in spatial domain.
