Abstract
Disclosed is a joint denoising and demosaicking method for a color RAW image guided by a monochrome image. The method comprises: constructing a synthetic image dataset of a monochrome-color binocular camera system for training and testing of network modules; constructing an aligned guidance image generation module by utilizing a structural correlation between a monochrome image and a color image, using a clean grayscale image corresponding to the RAW image as supervision, and training the aligned guidance image generation module by using a perceptual loss function to generate a high-quality aligned guidance image; using the generated aligned guidance image to guide the joint denoising and demosaicking process of the color RAW image; and training a guided denoising and demosaicking module ensure the accuracy of the color of the denoising and demosaicking result while accurately transferring the guidance image structure.
