图像因其直观形象的特性成为人们传递信息的一种重要载体，而传输中的图像或多或少的都带有噪声而影响图像质量．了解图像噪声类型是去除图像噪声的前提条件．研究分析了图像中三种常见噪声的直方图特性及成噪原理，最后从含噪图像直方图角度分析，观察其结果，得到三种噪声类型初步识别方法．

Image has become an important carrier of information transmission due to its characteristic of visual and vivid features. However, the image in transmission are more or less noisy and affect the image quality. To understand the types of image noise is a prerequisite for removing image noise. This paper mainly studied and analyzed the histogram characteristics of three kinds of common image noise, then analyzed from the noisy image histogram angle and observed the results, pro- posed three kinds of noise type identification method.
