Abstract

The invention relates to the technical field of artificial intelligence, and provides a face image restoration method and device, a face image restoration model, a medium and equipment. The method comprises the following steps: acquiring a to-be-restored image, and acquiring a face mark point image corresponding to the to-be-restored image; inputting the to-be-restored image and the face mark point image into a restoration model of the face image; carrying out at least two times of spatial feature conversion processing on the to-be-restored image and the face mark point image based on a restoration model of the face image to obtain fused face features; and performing convolution processing on the fused face features, and determining the output of the restoration model of the face image as a restored image corresponding to the to-be-restored image. According to the technical scheme, the face restoration accuracy can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular, to a method and device for repairing a human face image, a repair model for a human face image, and a computer-readable storage medium and electronic equipment for realizing the above method. Background technique [0002] Image restoration is used to restore the original picture of an image, specifically the process of reconstructing a degraded image into an original ideal image that is close to or completely degraded. [0003] A super-resolution reconstruction method is provided in the related art, which uses commonly used public face datasets to create low-resolution and corresponding high-resolution image datasets to train a machine learning model to determine a face super-resolution model. However, the image details caused by the image super-resolution process are lost and cannot be restored, resulting in low accuracy of face restoration. [0004] It c...
