Abstract
Examples of the present disclosure provide a method and an apparatus for denoising a low-light image, wherein the method includes: acquiring a low-light image in RAW domain; performing a preset image enhancement transformation on the low-light image in the RAW domain, and inputting the transformed image into a pre-trained denoising network model to obtain an output image; wherein, the denoising network model is trained based on sample images, and the sample images include a low-light image with simulated dead pixels and a noiseless image; performing an inverse transformation of the preset image enhancement transformation on the output image to obtain a denoised image. It can significantly reduce the influence of dead pixels of images on the process of denoising the low-light image and improve the quality of low-light image denoising.
