摘要： Noise in an image is reduced in a manner that takes into account edge information in one or more channels of the image. A first image is received that is formatted according to a red-green-blue (RGB) color model. The first image is converted from the RGB color model to a second color model that includes at least a luminance channel, a first chrominance channel, and a second chrominance channel that are representative of the first image. The first and second chrominance channels are each denoised in a manner that accounts at least for edge information in the luminance channel, and may also include edge information from other channels in a manner that accounts for per-channel noise characteristics. The luminance channel and denoised first and second chrominance channels are converted to a second image formatted according to the RGB color model that is a noise-reduced version of the first image.

摘要翻译： 图像中的噪声以考虑图像的一个或多个通道中的边缘信息的方式被减少。 接收到根据红 - 绿 - 蓝（RGB）颜色模型格式化的第一个图像。 第一图像从RGB颜色模型转换成包括代表第一图像的至少亮度通道，第一色度通道和第二色度通道的第二颜色模型。 第一和第二色度通道以至少考虑亮度通道中的边缘信息的方式去噪，并且还可以以考虑每通道噪声特性的方式包括来自其它通道的边缘信息。 将亮度通道和去噪的第一和第二色度通道转换为根据作为第一图像的噪声降低版本的RGB颜色模型格式化的第二图像。
