IMAGE PROCESSING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Title:

IMAGE PROCESSING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2023/137914

Kind Code:

A1

Abstract:

Embodiments of the present application relate to the technical field of image processing, and provide an image processing method and apparatus, an electronic device, and a storage medium. The method comprises: obtaining an original image to be processed; performing preliminary matting processing on the original image by means of a backbone network of a pre-trained matting model to obtain an initial foreground image; performing local refinement processing on an edge area of the initial foreground image by means of a fine-tuning network of the matting model to obtain a target foreground image; performing super-resolution reconstruction processing on the target foreground image by means of a pre-trained image reconstruction model to obtain a standard foreground image, wherein the resolution of the standard foreground image is higher than that of the target foreground image; and performing image fusion on the standard foreground image and a preset background image to obtain a target image. The embodiments of the present application can improve the image quality of the matted target image.
