浅析图像降噪的算法研究

摘要

In the generation and transmission processing, the image is inevitable to be contaminated by noise. Which the quality is impaired, not only can not meet people's visual effect, and the subsequent processing of the image is also very unfavorable. Therefore, in the pre-processing stage, it is necessary of image noise reduction, in order to improve the image SNR.%图像在生成和传输的过程中难免会受到噪声的污染，使得图像的质量受到损害，这不仅不符合人们的视觉效果，并且对图像的后续处理也很不利。因此，在图像的预处理阶段，有必要对图像进行降噪，以提高图像的信噪比。
