Title:
IMAGE PROCESSING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/279863
Kind Code:
A1
Abstract:
The present application provides an image processing method and apparatus, and an electronic device, and relates to the field of image processing. The image processing method comprises: acquiring an original image; adding a variance layer to the original image to obtain a layer set; processing the layer set by using a deep learning network model to obtain a first enhanced image; and enhancing the first enhanced image to obtain a second enhanced image. In the method, since a variance value corresponding to a pixel comprised in the added variance layer is determined by the photosensitivity corresponding to the original image, prior information can be added by means of adding the variance layer, so that noise reduction of different intensities can subsequently be performed according to different noise levels, thus retaining more details and achieving the purpose of improving the definition of the image.
