Due to the population of digital image and the broadening usage of digital image data, like interactive installation art, performance art, etc. In order to fulfill the requirements, improving the quality of digital images is very important. In this thesis, we apply a fast monochrome image noise reduction method to color images. We improve the method by adjusting parameters due to different properties of different color space layers. This thesis propose a fast and proper method for color image noise reduction, which is efficient removing Gaussian noise without blurring much image detail.
