More Information
Summary:The invention discloses a method and device of image denoising, relates to the field of image processing, and aims at solving the problem that the blurry degree of an image is high after denoising. The image denoising method comprises the steps of segmenting the image into multiple image regions; determining the image regions of which pixel value distributional difference characterization factors meet preset conditions in the multiple image regions as the image regions which are provided with colored noise points; conducting smoothing on the image regions which are provided with the colored noise points. 本发明公开种图像去噪的方法与装置，涉及图像处理领域，为解决去噪后图像模糊的程度高的问题。该图像去噪方法，包括：将图像分割为多个图像区域；将多个图像区域中像素值分布差异表征因子满足预定条件的图像区域确定为具有彩色噪声点的图像区域；对具有彩色噪声点的图像区域进行滤波。
