Abstract

The invention discloses a noise image generation method and device, electronic equipment and a storage medium, and belongs to the technical field of image processing. The noise image generation method comprises the following steps: acquiring a first image and a second image, wherein the first image is a noiseless image, and the second image is a noisy image acquired by using a target image sensor; determining a noise index value corresponding to the target image sensor; adding noise to the first image according to the noise index value to obtain a third image; and adjusting noise distribution of the third image according to the second image to obtain a noise image corresponding to the first image.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a noise image generation method, device, electronic equipment and storage medium. Background technique [0002] With the improvement of users' requirements on image quality, images containing noise captured by electronic devices cannot meet the needs of users more and more. Therefore, it is necessary to perform further noise reduction processing on the captured images. [0003] In the process of image denoising using traditional learning and deep learning and other related artificial intelligence algorithms, it is usually necessary to obtain or construct noise-noise-free sample image pairs to use these sample image pairs to train image denoising models. [0004] At present, when constructing training samples, the noise in the noise image usually uses random noise, so that the noise image obtained by noise synthesis cannot reflect the image sensor in...
