Abstract

The invention relates to the field of artificial intelligence, and discloses a face image resolution reconstruction method, device and equipment and a storage medium. The face image resolution reconstruction method comprises the steps: acquiring joint face data containing multiple different sources, wherein the joint face data comprises first face images with different resolutions and corresponding identity IDs; according to the identity ID, performing data alignment on the first face images from different sources to obtain multiple groups of first face images to be reconstructed; performing dynamic range compression on each group of first face images by adopting a preset homomorphic filter to obtain a plurality of groups of second face images; and inputting each group of second face images into a preset resolution reconstruction model to perform feature extraction and deconvolution sampling, and outputting a super-resolution face image corresponding to each identity ID. According to the invention, multi-source face image data can be obtained and high-efficiency and high-timeliness image super-resolution reconstruction can be carried out.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a face image resolution reconstruction method, device, equipment and storage medium. Background technique [0002] With the development of Internet big data, the application of user face image data is becoming more and more extensive, such as face recognition, face alignment, expression recognition and 3D face reconstruction, etc., all require clear and high-resolution face image data Only then can it be realized. Restoring a low-resolution image to a high-resolution image can be accomplished using an image reconstruction model. The widely used neural network model has outstanding performance in image resolution reconstruction. [0003] There are three existing image reconstruction methods: difference-based, reconstruction-based, and learning-based, but each is limited to single-frame image reconstruction, and batch image processing cannot be realized; the amount o...
